In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. The exact conservation laws include conservation of energy, and conservation of linear momentum, and also conservation of angular momentum, aswell as the conservation of electric charge
The two types of vaporization is EVAPORATION and BOILING. The difference is evaporation only occurs on a liquid’s surface; boiling occurs on both the surface and throughout the liquid.
BY the statement of the question it is clear that it is about an ideal gas - and hence if change in KE is about zero - then there will be no change of temperature.
