Question

which statement describes the relationship between temperature and the velocity of the molecules of water? (1 point) increasing the temperature causes the molecules to move faster. increasing the temperature causes the molecules to stick together. increasing the temperature causes the molecules to move slower. increasing the temperature causes the molecules to stop moving

Explanation:

According to the kinetic - molecular theory of matter, temperature is a measure of the average kinetic energy of the particles. As temperature increases, the kinetic energy of water molecules increases. Kinetic energy is related to the motion of particles ($KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity). Since the mass of water molecules remains constant (assuming no chemical change), an increase in kinetic energy means an increase in velocity. So, increasing the temperature causes the molecules to move faster.

Answer:

Increasing the temperature causes the molecules to move faster.
