1. if ice is heated at a constant pressure of 0.00512 atm, it . 2. if ice is heated at a constant pressure of 1 atm, it . 3. if the pressure of water vapor is increased at a constant temperature of 100 degrees celsius, it . 4. if the pressure of water vapor is increased at a constant temperature of -50 degrees celsius, it .

sublime, melt, condense, deposit

Explanation:

1. When ice is warmed at a steady pressure 0.00512 atm, it will be sublime.  

2. It will be melt when ice is warmed at a consistent pressure of 1 atm.

3. If water vapour pressure is continued to increase at a temperature of 100  C, it will be condense.  

4. If water vapour pressure is continued to increase at a temperature of -50 C, it will be deposited.
