Athermometer is placed in water in order to measure the water’s temperature. what would cause the liquid in the thermometer to rise? a)the molecules in the water move closer together. b)the molecules in the thermometer’s liquid spread apart. c)the kinetic energy of the water molecules decreases. d)the kinetic energy of the thermometer’s liquid molecules decreases.

B. The molecules in the thermometer’s liquid spread apart.

Explanation:

The liquid in the thermometer will only rise if the molecules in the liquid that is in the thermometer will begin to spread apart.

This would only occur if the water is hot (or warm).

This is because if the temperature in the water around the thermometer's bulb heats up, the molecules inside the thermometer will begin to expand and spread apart, causing the liquid rises in the glass tube.
