This increase in temperature increases the ______________ of the gas, which results in the gas particles moving faster and colliding more often with the wall of the container. These collisions are what increase the pressure of the gas on the balloon, and ultimately cause the balloon to stretch out.

C kinetic energy

The correct answer is C, kinetic energy.

When the temperature of a gas increases, the kinetic energy of the gas particles also increases. Kinetic energy is the energy associated with the motion of particles. As the particles move faster, they collide more frequently with the wall of the container.

These collisions between the gas particles and the container walls result in a change in momentum, which causes a force to be exerted on the walls. This force creates pressure on the walls of the container. Pressure is the force per unit area.

As the gas particles move faster and collide more often with the walls, the pressure exerted by the gas increases. In the case of a balloon, this increase in pressure causes the balloon to stretch out.

To arrive at this answer, it is important to understand the relationship between temperature and kinetic energy. The temperature of a gas is directly proportional to the average kinetic energy of its particles, according to the kinetic theory of gases.

The correct answer is C) kinetic energy.
