General Chemistry I

Question

A substance is initially at T= 5C and P = 0.1 atm. When the temperature is held constant and the pressure is increased to 1.0 atm, which process occurs?

Answer 1

At constant temperature PV is a constant or

P_initial V_initial = P_final V_final

Therefore as P increases V will decrease

V_final = V_initial x (P_initial / P_final) = V_initial x (0.1 atm / 1 atm) = V_initial / 10
