Type Problem
A steel tank contains a gas at 27°C and a pressure of 12.0 atms. Determine the gas
pressure when the tank is heated to 100.°C.
Reasoning that an increase in temperature will cause an increase in pressure
at constant volume, you know the pressure must be multiplied by a fraction that
has a larger numerator than denominator. The fraction must be. So
Or you can use the formula:
Another Example
At 120.°C, the pressure of a sample of nitrogen is 1.07 atm. What will the
pressure be at 205°C, assuming constant volume?
