<u>Answer:</u>

<em>When the volume is constant the pressure increases with temperature.  </em>

<em>Gay Lussac’s law precisely explains the relation between pressure and temperature of a system which has constant volume.</em> In a system which has constant volume an increase in temperature indicates increase in temperature as well.
