The specific heat of the human body calculated from the measured values of individual tissues is 2.98 kJ · kg−1 · °C−1. This is 17% lower than the earlier wider used one based on non measured values of 3.47 kJ · kg−1· °C−1.
The resulting reaction releases heat and thus warms the beverage which it is surrounding. [1] The heating agent and responsible reaction vary from product to product. Calcium oxide is used in the following reaction: CaO(s)+ H 2 O(l) → Ca(OH) 2 (s) Copper sulfate and powdered zinc can also be used, but this process is less efficient:

For that reason, the average Energy Star-certified smart thermostat can save about 8% of a homeowner's annual heating and cooling bills, according to Consumer Reports. Check for tax incentives and ...
An automotive thermoelectric generator (ATEG) is a device that converts some of the waste heat of an internal combustion engine (IC) into electricity using the Seebeck Effect. A typical ATEG consists of four main elements: A hot-side heat exchanger, a cold-side heat exchanger, thermoelectric materials, and a compression assembly system. ATEGs ...
Heater core (arrowed) in the partially disassembled dashboard of a BMW E32.. The internal combustion engine in most cars and trucks is cooled by a water and antifreeze mixture that is circulated through the engine and radiator by a water pump to enable the radiator to give off engine heat to the atmosphere.
Heat cost allocators are devices attached to individual radiators in buildings that measure the total heat output of the individual radiator. Heat cost allocators can be either electronic, where one or two electronic thermosensors [1] and a microcontroller are used to calculate the heat consumption of radiator by the temperature difference between the radiator and the air in room, [2] [3] or ...
