We are most likely to find water in the form of gas in the atmosphere.
It's actually C because the rock cooled fast
Do you have the picture of the data?
If ice is warmed and becomes a liquid, the process is endothermic.
The process requires heat in order to proceed. If ice stays in a very cold place, it will not melt unless it's heated. If ice is placed outside where it melts on its own, it gets the heat from the surroundings.
