The picture shows two completely identical mason jars. They're both filled with the same gas, only one of them has more in it (more molecules). What can you say about the pressures of both jars?

• P₁ > P₂ (greater pressure in jar 1)

• P₁< P₂ (greater pressure in jar 2)

• P₁ = P₂ (same pressure in both)

When thermal energy is added to a substance, the substance's particles move:

• More rapidly at an increased diestance from each other.
• More rapidly with less distance between each other.
• More slowly with a greater distance between each other.
• More slowly with a reduced distance between each other.
