As lungs expand and fill with air, the diaphragm lowers enabling for the lungs to spread and for more air to enter. When you exhale, the diaphragm retracts and helps push out CO2 out of the lungs.
Answer:
How Convection Works. Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.
Explanation: Hope this helps.
<span>Sweating makes the body cool after wetness goes away. This includes the factors in cooling your body by sweating are molecules colliding with multiple angles and speeds, hydrogen bonds are relatively weak and water has more energy at the body surface. So by all these reasons cooling makes the body cool through sweating.</span>
The transmission of heat requiring the movement of a liquid or a gas is Convection.
Convection: the heat transfer due to bulk movement of molecules.
