Question

which of the following involves the particles moving the fastest?
a room temperature water
b glass of ice water
c ice cube
d boiling water

Explanation:

The kinetic energy of particles is related to temperature; higher temperature means faster - moving particles. An ice cube (c) is a solid with low - energy, slow - moving particles. A glass of ice water (b) has a lower temperature than room - temperature water (a). Boiling water (d) has a much higher temperature (100°C at standard pressure) compared to room - temperature water, ice water, and an ice cube. So, the particles in boiling water move the fastest.

Answer:

d. boiling water
