The number of collisions between water particles increases.

Answer 1

The speed of the water particles increases.

The number of collisions between water particles increases.

Step-by-step explanation:

When water particles are heated, the speed of the particles increases and the number of collisions between the water particles also increases.

• Heating increases the thermal energy of the system
• When water particles gain more thermal energy, their average speed increases drastically.
• Also, the frequency of collisions increases due to the gain in thermal energy of the system.
