How much thermal energy is needed to change 3.00times 10 power of 2g of ice at -30.0C to water vapor at 130.0C?

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
