Energy is measured in many ways. One of the basic measuring blocks is called a Btu. This stands for British thermal unit and was invented by, of course, the English. Btu is the amount of heat energy it takes to raise the temperature of one pound of water by one degree Fahrenheit, at...
A heat engine is a device that converts part of heat absorbed into work. It extracts energy in the form of heat from a heat source and does useful work as it continuously repeats a thermodynamic cycle, discarding some heat to a heat sink. To convert h

What is the difference between a kilowatt hour (kWh) and a kilowatt (KW)? A kilowatt (kW) is a unit of power that measures the rate at which energy is used or produced, while a kilowatt-hour (kWh) is a unit of energy that represents the amount of electricity consumed over time. Ess...
Thermodynamicsis the branch of physics dealing with the work and energy of a system. Work, energy and heat all have the same units in physics despite having different meanings and applications. The SI (standard international) unit of heat is the joule. Work is defined as force multiplied by ...
energy-efficient home heating on all but the coldest days. When the temperature outside drops too low for the heat pump to operate effectively, the system will instead use the furnace to generate heat. This kind of system is often called adual fuel system– it is very energy efficient ...
