The temperature of 500 mL of water is 16°C. What happens to the water
when thermal energy is transferred to it?
A. The temperature of the water decreases because the average
kinetic energy of the water molecules decreases.
B. The volume of the water decreases because thermal energy
decreases as volume decreases.
C. The temperature of the water increases because the average
kinetic energy of the water molecules increases.
D. The volume of the water increases because thermal energy
increases as volume increases.
