Question

bromine gas in a container is heated over a flame. what happens to the average kinetic energy of the bromine particles?
○ it decreases rapidly.
○ it increases quickly.
○ it remains the same.
○ it decreases slowly.

Explanation:

The average kinetic energy of gas particles is directly proportional to the absolute temperature of the gas. When bromine gas is heated, its temperature rises rapidly, so the average kinetic energy of its particles increases quickly.

Answer:

It increases quickly.
