Heat gain refers to the process of gaining heat, typically from external sources like sunlight or equipment. Heat loss, on the other hand, refers to the process of losing heat, either through conduction, convection, or radiation. Both processes are important to consider in maintaining thermal comfort in a building.

Is melting heat gain or heat loss?
Melting is a process that requires heat to change a solid substance into a liquid, so it is a heat gain process. Heat is absorbed to break the bonds between the molecules in the solid and allow them to move more freely as a liquid.
What are the two factors that affect the rate of heat gain or loss of am object through radiation?
The two factors that affect the rate of heat gain or loss of an object through radiation are the temperature difference between the object and its surroundings and the emissivity of the object's surface. The temperature difference plays a role in determining the direction and magnitude of heat transfer, while emissivity quantifies how efficiently an object emits or absorbs thermal radiation.
What is a physical change in matter caused by a loss or gain of heat called?
A physical change in matter caused by a loss or gain of heat is called a thermal change.
How can heat loss can be increased?
Heat loss can be increased by increasing the temperature difference between the object and its surroundings, increasing the surface area of the object, and decreasing the insulation around the object. Additionally, air movement can increase heat loss through convection.
What term is used to describe when heat gain is equal to heat loss?
The term used to describe when heat gain is equal to heat loss is thermal equilibrium. This means that there is no net change in temperature because the heat gained by a system is equal to the heat lost by the system.
Is precipitation heat loss or heat gain?
heat loss
What is difference between abnormal loss and abnormal gain?
if the actual loss is greater than normal loss. it is known as abnormal loss but if the actual loss is less than normal loss a gain is obtained which is called abnormal gain or effectiveness
Requires a gain or loss of heat energy?
A temperature change requires as gain or loss of heat energy.
Realized gain or loss is measured by the difference between the amount realized from the sale or other disposition of property and the property's adjusted basis at the date of disposition?
Realized gain or loss is measured by the difference between the amount realized from the sale or other disposition of property and the property's adjusted basis at the date of dispositionAnswer: TrueRealized gain or loss is the difference between the amount realized and the property's adjusted basis.
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
What is adiabatic combustion?
NO Heat Loss , No Heat gain

Difference between debit and credit in accounting?
A debit is money paid out or a loss, a credit in income or a gain.
What is a physical change in matter caused by a loss or gain of heat called?
A physical change in matter caused by a loss or gain of heat is called a thermal change.
