It's a chemical change because a new compound is formed
Answer:
2.62 atm
Explanation:
1 atm = 14.6959 psi
38.5 / 14.6959 = 2.62 atm
The heat used in phase changes is calculated by multiplying the mass of the substance by the energy of the phase change. In this case, for liquid to boil, we would find total heat by multiply the mass of liquid by the latent heat of vaporization (Hvap). If we are instead given the Hvap and the total heat of 1 kJ, we would divide 1 kJ by the Hvap (which is usually in kJ/kg) to get the mass of liquid boiled (in kg).
