Hydrogen phase transition

A sample of hydrogen at a pressure of 7.10×10-2 atm and a temperature of 26.4 K is compressed at constant temperature to a pressure of 18.5


Which of the following are true?
1. One or more phase changes will occur
2. The sample is initially a solid.
3. The liquid initially present will vaporize.
4. The final state of the substance is a liquid


The sample is initially a gas


MY ANSWER: 
I feel that one or more phases will change and that the liquid present will vaporize as it surpasses the supercritical point.
