Assume the temperature is constant. Standard pressure is 101.3 kPa. Standard temperature is 273.15 K Show work

1) What is the new volume when a 100.0 cm3 container at 120.0 kPa is expanded until the pressure is 60.0 kPa?

2) What is the new volume when a 50.0 cm3 container at standard pressure is expanded is expanded until the new pressure is 25.0 kPa?

3) What is the new volume when a 50.0 cm3 container at standard pressure is compressed until the new pressure is 200.0 kPa?
