Question

which of the following is an example of thermal expansion? an example of thermal expansion is dropping a marble in a cylinder of liquid. an example of thermal expansion is ice cubes melting in a glass of lemonade. an example of thermal expansion is the liquid inside a thermometer rises. an example of thermal expansion is ice is less dense than liquid water.

Explanation:

Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. When the temperature of the liquid in a thermometer increases, it expands and rises. Dropping a marble in liquid is about buoyancy, ice - cubes melting is a phase - change, and ice being less dense than water is due to its molecular structure.

Answer:

An example of thermal expansion is the liquid inside a thermometer rises.
