4. When a beaker of water is heated its volume increases a little. What is happening to

the particles in the liquid?
a. speed up and move closer
b. slow down and move closer
c. speed down and move farther apart

Answer 1

Answer: They speed up and move farther apart.

Explanation: With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates. The volume increases as they start moving apart from each other.
