What happens to the volume of gas if its temperature is increased? Increases Decreases Stays the same Not enough information

## Step 1<br />The problem is asking about the behavior of gases when their temperature is increased. This is a fundamental concept in thermodynamics, specifically the ideal gas law.<br /><br />## Step 2<br />The ideal gas law is a theoretical model that assumes gases behave in a certain way under certain conditions. The law is given by the equation:<br />### \( PV = nRT \)<br />where \( P \) is the pressure, \( V \) is the volume, \( n \) is the number of moles, \( R \) is the gas constant, and \( T \) is the temperature.<br /><br />## Step 3<br />According to the ideal gas law, if the pressure and the number of moles of gas are constant, the volume of the gas is directly proportional to its temperature. This means that if the temperature increases, the volume of the gas also increases, assuming the pressure and the number of moles of gas remain constant.
