Question

1. compare the motion of molecules of a hot tea to the molecules of a cold tea

Explanation:

According to the kinetic - molecular theory of matter, temperature is a measure of the average kinetic energy of the molecules. Hotter substances have higher temperatures. Molecules in a hot tea have higher average kinetic energy than those in a cold tea. Since kinetic energy \(K = \frac{1}{2}mv^{2}\) (where \(m\) is the mass of the molecule and \(v\) is the velocity of the molecule, and assuming the mass of water molecules in both hot and cold tea is the same), molecules in hot tea move faster on average than molecules in cold tea.

Answer:

Molecules in hot tea move faster on average than molecules in cold tea.
