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.

It increases quickly.

Explanation: Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

R = gas constant

T = temperature of system

From the equation, it is visible that kinetic energy is directly related to the temperature of the system. So, when bromine gas is heated , temperature is more and thus average kinetic energy of the system is more.

If kinetic energy of particles is more, the movement of particles will be more.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
