Daytime temperatures on Mercury are extremely hot because: it is close to the sun
there are volcanoes
one side is facing the sun
it has long days
it gives off internal heat

*multiple choice*

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
