easy · Enhanced ACT science
A heater is used to raise the temperature of a block of ice from -10^circC to 0^circC.
Which statement correctly describes the molecules in the ice during this process?
- The molecules stop moving entirely because ice is a rigid solid structure.
- The molecules begin to move further apart, immediately turning the solid into a liquid.
- The number of protons in each water molecule increases due to the added heat energy.
- The kinetic energy of the molecules increases, causing them to vibrate faster.
