What causes thermal energy transfer?
Thermal energy transfer occurs due to the movement of heat from a hotter object to a colder object through conduction, convection, or radiation. The underlying principle is to achieve thermal equilibrium between the objects involved.
How does a substance gain thermal energy?
A substance gains thermal energy when it absorbs heat from its surroundings. This can happen through various processes, such as conduction, convection, or radiation. The thermal energy causes the particles in the substance to move faster, increasing its temperature.
How is energy transferred from a cup of boiling water?
Energy is transferred from a cup of boiling water through convection, conduction, and radiation. Convection causes the hot water at the bottom to rise, transferring heat to the cooler water at the top. Conduction transfers heat from the water to the cup, and radiation emits heat in the form of infrared waves.
What type of heat transfer causes heat to rise and cold air to fall radiation conduction or convection?
Convection is the type of heat transfer that causes hot air to rise and cold air to fall. This is because warmer air is less dense and tends to move upwards, while colder, denser air sinks. Radiation and conduction do not directly cause this vertical movement of air.
What causes the transfer of thermal energy?
Thermal energy transfer occurs through conduction (direct contact), convection (movement of fluids or gases), and radiation (electromagnetic waves). Heat flows from areas of higher temperature to lower temperature until equilibrium is reached.

What are the three processes of heat transfer?
The three methods of heat transfer are: (1) Conduction - particles bump into other particles, transferring energy. (2) Convection - moving masses carry heat with them. Especially, hot air (for example) tends to rise up, because of its lower density - the heat difference itself causes the currents. (3) Radiation. Objects radiate electromagnetic radiation, depending on their temperature. (The amount of energy radiated increases quickly at higher temperatures.)
What eventually causes a thermal to dissipate?
Thermal dissipation occurs when the heat energy stored in an object (such as a heated material or component) is transferred to its surroundings, resulting in a decrease in temperature. This transfer of heat can happen through conduction, convection, or radiation, allowing the object to return to thermal equilibrium with its surroundings.
How come when you are away from the stove you still feel the heat is it because of convection evaporation or conduction?
Neither, it is radiation that causes you to feel the heat from a distance.
What moves air and thermal energy throughout the troposphere?
Air and thermal energy are moved throughout the troposphere primarily through atmospheric circulation driven by uneven heating of Earth's surface by the sun. This causes convection currents, jet streams, and other wind patterns that distribute air and heat. Additionally, mechanisms such as conduction and radiation also play a role in transferring thermal energy.

What causes a substance to cool down?
A substance cools down when it releases heat energy to its surroundings through processes like conduction, convection, and radiation. This can happen when the substance is in contact with a cooler object, when it loses heat to the air or water around it, or when it emits thermal radiation.
How do three types of heat transfer work together to heat the trosphere?
The three types of heat transfer - conduction, convection, and radiation - work together to heat the troposphere. Conduction occurs when heat is transferred through direct contact with Earth's surface. Convection then causes warm air to rise and cool air to sink, creating vertical movement of air and distributing heat. Radiation involves the sun's energy being absorbed by the atmosphere, which warms the air as it travels downwards.
What are the three changes that causes heat in substances?
1. melting 2.boiling 3.freezing
How do conduction convection and radiation affect the movement and temperature of air near the ocean?
Conduction, convection and radiation affects the movement and temperature of air near the ocean. Conduction causes difference in temperatures. For example, during a hot day, land heats up more quickly than water. Water is a better conductor of heat. The air near the land's surface is heated due to conduction and radiation. It expands and rises since it is lighter than surrounding air. This is called convection. To replace the air that rose, the air from the sea's surface blows to land.
