A sample of H2 gas is kept in an 800.0 mL container at 33.0 oC and exerts a pressure of 1255 torr. At what temperature will this same sample of gas exert a pressure of 0.900 atm in a 2.00L container.

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
