Athermometer is placed in water in order to measure the water’s temperature. what would cause the liquid in the thermometer to drop? . .
a. the molecules in the water spread apart. .
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 increases

The correct answer is (c).

Explanation:

Thermometer is a device which measures the temperature.

Temperature is a measures of the average kinetic energy of the particles in the substance. It measures how the hot or cold an object is.

In the given problem, a thermometer is placed in water in order to measure the water’s temperature. When the kinetic energy of the water molecules decreases then the thermometer shows the drop in the temperature.

When the kinetic energy of the water molecules increases then the thermometer shows the rise in the temperature.

Therefore, the correct option is (c).

think its the third option
