On the basis of Boyle's law, explain why
mountaineers carry oxygen cylinders with them.

Boyle's Law states that 'at constant temperature, the pressure of a fixed amount of gas varies inversely with the volume of the gas. Mountaineers have to carry oxygen cylinders with them to restore normal breathing because at high altitude the density of air is less.

Explanation:

I majored in Chemistry.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

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.
