On what factor does the quantity of heat energy lost or gained by a body depends.
1 Answer
Heat lost or gained depends on three factors which are given below:
- Mass of body
- specific heat capacity of the body
- difference in temperature of a body.
Heat loss, measured in kW or BTUs, reflects the total transfer of heat through the fabric of the building from the inside out. ... The opposite of heat loss is heat gain, also referred to as solar gain. Heat gain occurs when when warmth comes into the space via radiant heat as the sun shines through the glass.we learned what heat does to an object when it is gained or released. Heat gains or losses result in changes in temperature, changes in state or the performance of work. Heat is a transfer of energy. When gained or lost by an object, there will be corresponding energy changes within that object.
The formula used to calculate heat gain from thermal conduction (outside ambient temperature during the cooling season) is the same basic formula as the Heat Loss Formula, [(Square Foot Area) x (U-Value) x (Temperature Difference)].The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body.Matter can exist in three different states: solid, liquid or gas. In evaporation, matter changes from a liquid to a gas. ... Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.
a rise in temperature of a body when obtaining heat by radiation or conduction from an outside source, leading to an increase in METABOLIC RATE in all organs. see TEMPERATURE REGULATION.Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material. Different materials have greater or lesser resistance to heat transfer, making them better insulators or better conductors.
