Question
Physics Question on thermal properties of matter
A quanity of heat required to change the unit mass of a solid substance, from solid state to liquid state, while the temperature remains constant, is known as
A
hoar frost
B
sublimation
C
latent heat
D
latent heat of fusion
Answer
latent heat of fusion
Explanation
Solution
Latent heat is defined as the amount of heat required to change the state of a substance, while the temperature remains constant. Here, the state changes from solid to liquid, hence, it is defined as the latent heat of fusion.
