True or False: According to-Lussac's Law, the pressure of a gas is directly proportional to its temperature when volume is constant. A. False B. True

## Step 1<br />Lussac's Law, also known as Gay-Lussac's Law, is a principle in chemistry that states that the pressure of a gas is directly proportional to its absolute temperature, provided the volume is kept constant. This means that if the temperature of a gas increases, the pressure will also increase, and vice versa, as long as the volume does not change.<br /><br />## Step 2<br />The mathematical representation of Lussac's Law is \( P \propto T \), where \( P \) is the pressure of the gas and \( T \) is the absolute temperature of the gas.<br /><br />## Step 3<br />Given the statement in the problem, "According to Lussac's Law, the pressure of a gas is directly proportional to its temperature when volume is constant", we can see that this statement is a direct representation of Lussac's Law.
