True
False
Choose the correct statement(s) about how pressure can effect changes of states of matter
If pressure if lower, you need a higher temperature to change the state of matter
If the pressure is higher, you need a higher temperature to change the state of matter
If pressure if lower, you need a lower temperature to change to state of matter
