An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy.
In physics, energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement in the International System of Units (SI) of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of one metre against a force of one newton.
The joule is a derived unit of energy in the International System of Units. It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
In thermodynamics, the specific heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR.
A heat pump is a device that transfers thermal energy between spaces, usually between an enclosed space and the outdoors. When used to heat a building, the energy is transferred from the outside into the building. A heat pump can also work as an air conditioner by transferring heat from the building to the outside.
The Miami Heat are an American professional basketball team based in Miami. The Heat compete in the National Basketball Association (NBA) as a member of the league's Eastern Conference Southeast Division. The club plays its home games at FTX Arena, and has won three NBA championships.
A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K).
A heat wave, or heatwave, is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is usually measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be called a heat wave in a cooler area if they are outside the normal climate pattern for that area.
Patrick James Riley is an American professional basketball executive and a former coach and player in the National Basketball Association (NBA). He has been the team president of the Miami Heat since 1995, and he also served as the team's head coach from 1995 to 2003 and again from 2005 to 2008. Regarded as one of the greatest NBA coaches of all time, Riley has won five NBA championships as a head coach, four with the Los Angeles Lakers during their Showtime era in the 1980s and one with the Heat in 2006. Riley is a nine-time NBA champion across his tenures as a player (1972), assistant coach (1980), head coach, and executive.
Alonzo Harding Mourning Jr. is an American professional basketball executive and former player. Mourning played most of his 15-year National Basketball Association (NBA) career for the Miami Heat. Since June 2009, Mourning has served as vice president of player programs and development for the Heat.
Dwyane Tyrone Wade Jr. is an American former professional basketball player. Wade spent the majority of his 16-year career playing for the Miami Heat of the National Basketball Association (NBA) and won three NBA championships, was a 13-time NBA All-Star, an 8-time member of the All-NBA Team, and a 3-time member of the All-Defensive Team. Wade is also Miami's all-time leader in points, games, assists, steals, shots made, and shots taken. Wade is currently the host of the American adaptation of The Cube.
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by use of powered "air conditioners" or a variety of other methods, including passive cooling and ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC).
Erik Jon Spoelstra is an American professional basketball coach and former player who is the head coach for the Miami Heat of the National Basketball Association (NBA). He has won two NBA championships as the head coach of the Heat. A Filipino American, Spoelstra is the first Asian-American head coach in the history of the four major North American sports leagues and the first Asian-American head coach to win an NBA title.
In thermodynamics, heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter.
Temperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter. Temperature should not be confused with heat.
Jimmy Butler III is an American professional basketball player for the Miami Heat of the National Basketball Association (NBA). Nicknamed "Jimmy Buckets", he played one year of college basketball for Tyler Junior College before transferring to Marquette University.
The 2011 NBA Finals was the championship series of the National Basketball Association's (NBA) 2010–11 season. The Western Conference champion Dallas Mavericks defeated the Eastern Conference champion Miami Heat in six games to win their first NBA championship. The series was held from May 31 to June 12, 2011. Mavericks forward and German player Dirk Nowitzki was named the Finals MVP, becoming the second European to win the award after Tony Parker (2007) and the first German player to do so. The series was a rematch of the 2006 NBA Finals, which the Heat had won in six games to win their first NBA championship.
