Athermometer is placed in water in order to measure the water’s temperature. what would cause the liquid in the thermometer to rise?

The molecules in the thermometer's liquid would spread apart.

Explanation:

The liquid in a thermometer reacts to the temperature of a substance, because the thermal energy of the water is being transferred into the thermometer's liquid. The water has a high temperature, because the kinetic energy of the water has decreased causing the thermometer's liquid to spread apart. In addition, temperature reacts to the amount of kinetic energy between the molecules of substance. For example, if a substance's molecules have a low kinetic energy, then the temperature of said substance will decrease and vice versa.

Hope this helps you! :)
