The volume of gas is 252 mL at 340.0 kPa pressure. What will the volume be when the pressure is reduced to 50.0 kPa? Temperature is constant

The density of the solid phase of a substance is 0.90 g/cm3 and the density of the liquid phase is 1.0 g/cm3. a large increase in pressure will a. lower the freezing point b. raise the freezing point c. lower the boiling point d. raise the triple point e. lower the triple point
