Practice question · Numerical answer
A sample of gas occupies 3.0 L at 300 K. If the pressure is held constant and the temperature is raised to 400 K, what is the new volume in litres, to one decimal place?
Hints
- At constant pressure, volume is proportional to absolute temperature.
- Compute 3.0 x 400/300.

Why
Charles’s law gives L. Note that both temperatures are already in kelvin, as every gas law requires.
