Yeah - but remember the increase in temp is always on the kelvin scale. Proportions are related to zero kelvin.
yes it is changing. It's increasing with the temperature.
what happens at the molecular level when water evaporates?
The teamperature does not change
As the temperature drops the vapor pressure of water also decreases and the molecular movement of water decreases. Once the temperature drops enough the molecular movements may even be slow enough for water to become a solid that we know as ice
for example :ice can change the temperature of water
mean molecular speed varies as the square root of temp, so the temp has to change by a factor of 4 for the speed to change by a factor of two...hope I am interpreting your question properly

yes it can like when it temperature of a pot of water, or it can change the direction and speed of a baseball.

Physical change.
No
There is no molecular change ;)
Water does change as it melts from a solid to liquid. That's the change. Its molecules speed up and separate from the lattice structure structure of the ice and become fluid. This is called a physical change because the water molecules themselves do not undergo a change. Solid water and liquid water are still water.If you're talking about temperature, the temperature does not change during the phase change. That's because the heat energy is being used to remove water molecules from the lattice structure. Once all of the water molecules a separated, the temperature can increase.
