a thermometer is placed in water in order to measure the waters temperature. what would cause the thermometer to drop? the molecules in the water spread apart. the molecules in the thermometers liquid spread apart. the kinetic energy of the water molecules decreases. the kinetic energy of the thermometers liquid molecules increases.

a thermometer is placed in water in order to measure the waters temperature. what would cause the thermometer to drop? the molecules in the water spread apart. the molecules in the thermometers liquid spread apart. the kinetic energy of the water molecules decreases. the kinetic energy of the thermometers liquid molecules increases.

Answer

Brief Explanations:

Temperature is related to the average kinetic energy of molecules. When the kinetic energy of water molecules decreases, the water cools down, and the thermometer reading drops as it measures the water's temperature. Molecules spreading apart is related to phase - change or expansion due to heating, not cooling. An increase in the kinetic energy of the thermometer's liquid molecules would cause the thermometer to rise.

Answer:

The kinetic energy of the water molecules decreases.
