How is a change in temperature related to the pressure of a contained gas? As temperature increases pressure remains constant. As temperature increases pressure increases. As temperature increases pressure either increases or decreases depending on the gas. As temperature increases pressure decreases.

Question

How is a change in temperature related to the pressure of a contained gas? As temperature increases pressure remains constant. As temperature increases pressure increases. As temperature increases pressure either increases or decreases depending on the gas. As temperature increases pressure decreases.

Answer 1

## Step 1The relationship between the temperature and pressure of a contained gas is described by Gay-Lussac's Law. This law states that the pressure of a gas is directly proportional to its absolute temperature, provided the volume and the amount of gas remain constant. ## Step 2This means that if the temperature of the gas increases, the pressure of the gas also increases, assuming the volume and the amount of gas remain constant. ## Step 3Therefore, the correct answer is "As temperature increases, pressure increases."
