B) lever and pulley is the answer
Melting point is when a mass goes from solid to liquid, whereas boiling point is when a mass goes from liquid to gas. I hope this helps.
The temperature of an air parcel and the kinetic energy of an air parcel are directly related. this means that as the temperature of the air parcel increases, the kinetic energy increases.
<h3>
What is temperature?</h3>
Temperature is the measure of degree of hotness or coldness of a body.
Temperature is also the measure of the average kinetic energy of a system.
When the heat is applied to body, its temperature increases as the body gains heat.
Thus, the temperature of an air parcel and the kinetic energy of an air parcel are directly related. this means that as the temperature of the air parcel increases, the kinetic energy increases.
