Question

The speed of molecules is indirectly related to a measurement called _____.

heat flow
temperature
friction
energy

Answer 1

The correct choice is

temperature

Step-by-step explanation:

According to kinetic molecular theory, the average molecular kinetic energy is directly proportional to the temperature. we know that kinetic energy is directly proportional to the square of the speed of the molecule. hence the square of the speed is directly proportional to the temperature.

Answer 2

The speed of molecules is indirectly related to a measurement called temperature.
