When a beaker of water is heated over a bunsen burner, the volume increases slightly. what is the most likely reason for the small increase in volume?
a
the water molecules are getting smaller.
b
the water molecules are getting bigger.
c
the water molecules are moving faster.
d
the water molecules are moving slower.

most likely c

Explanation:

the volume is increased by the quickly moving water particles

Option C

Explanation:

The molecules has kinetic energy and potential energy both.  When the water molecules were heated  on a Bunsen Burner then there can be a slight increase in the volume of the water.

This is because upon heating the kinetic energy of the molecules increases and it starts moving fastly.

Due to the movement of the particles, they become far from each other and there is a slight increase in the volume of the water.
