Question

on a temperature versus time graph, how does the temperature at the beginning of a change is state compare with the temperature at the end of the change

Answer 1

Its decreasing read it carefully

Answer 2

Answer:

The temperature will remain the same.

Explanation:

When a material goes through a change of state, the temperature remains the same as witnessed on a temperature versus the time graph. Each change of state, that is, condensation, evaporation, melting, and fusion needs the withdrawal or supplementation of energy called latent heat. At the point of a change of state, there is no change in temperature. Though, in between the changes of states, the modifications in temperatures are brought about by the sensible heat.
