Yes. Typically, a gas will approximately expand according to the ideal gas law; this means that if you double the temperature (expressed in kelvin), and keep the temperature constant, the volume will approximately double.

Yes when gas is heated, the molecules spread out. This also increases the volume. It is this method that hot air balloons are able to fly.
