Yes on both counts. But hot air balloons need considerably more help - they use propane burners to heat the air inside the balloon.
because its really hot it uses its heat
As the earth is heated by the sun, bubbles of air rise upward from the warm surface.
I think you mean why does hot sand heat the air by convection... The sand is heated by the sun, and the air is touching the sand, which is hot, so by convection, the sand is heating the air.
From the Sun. (The Sun's energy causes water to evaporate and heat air. the latent heat of the evaporation and the hot air drive the storm).
Yes. Convection causes it, which is one of the three types of heat. It spreads the heat around and gets the molecules moving. The other two types of heat are conduction, which is when something is heated by directly touching something hot, like touching a stove, and radiation, which is when heat travels in waves, like the sun.
The main method of heat transfer in the atmosphere is through convection. As the Earth's surface is heated by the Sun, the air near the surface becomes warmer and less dense, causing it to rise. This upward movement of air transfers heat throughout the atmosphere.
The sun is a source of energy. The energy is absorbed by the earth on dry land or water in a river or ocean in the form of heat. The temperature rises when the sun shines, whether it shines on water or land. On land, the temperature rise causes the surrounding to heat up. The air above the hot land rises and form a low pressure. At sea, the temperature rise causes water to evaporate to increase the air humidity above the sea and form clouds in the sky.
Modes for heat transfer are:convection (the air around a warm object gets hot and rises)conduction(direct contact)radiation(like the heat you feel from the sun)
Air becomes hot on a sunny day primarily due to the sun's radiation. When sunlight reaches the Earth's surface, it warms the ground, which in turn heats the air directly above it through conduction. Additionally, the warm ground causes air to rise, creating convection currents that distribute the heat. As this process continues, the overall temperature of the air increases.
The sun affects the air you need to breathe directly. When the sun is hot, it warms up the air in the atmosphere which means that you will breathe in hot air.
Energy from the sun heats the ocean surface, causing water to evaporate and rise, creating warm, moist air. This warm, moist air then condenses and releases latent heat, fueling the storm’s circulation and intensifying the hurricane's development. The process continues as the warm air rises, creating a cycle that strengthens the storm.
Water conducts heat much better than air, and that is due greater density of water. Therefore, your body will receive more heat from hot water than from hot air that is in contact with your skin.
