The particles absorb energy and their particle violence increases (particle violence is how much the particle vibrates in a solid, or how fast a particle moves in a liquid or gas).
- In conduction, this is caused by the particles of the hotter substance colliding with the particles of the cooler substance and thereby increasing their movement (kinetic energy). Imagine you are standing still and someone running suddenly collides with you. You will be sent staggering as you are pushed by the person, and the person will be slowed down by the resistance of pushing you over. That is the best way I can explain conduction.
- Radiation is harder to explain as it does not happen purely on a physical level. Radiation is the transmission of energy in the form of a wave, like light (Electromagnetic Radiation) or sound. Particles reflect, transmit, and absorb this radiation, to varying degrees. Mirrors reflect most light, air transmits most light, and black fabric absorbs a lot of light. The more it absorbs, the hotter it becomes as the wave energy (in this case light) is transformed into kinetic energy.
This is to the best of my understanding. Hope it helps.
What else can I help you with?
When the room becomes warm when the furnace is turned on which is the answer conduction convection radiation?
The answer is convection. Convection is the transfer of heat through the movement of fluids (liquids or gases), such as air becoming warm and rising as it is heated by the furnace, creating a convection current that warms the room.
How does heat travel by conduction radiation and convection?
Heat travels by conduction through direct contact between particles. In radiation, heat is transferred through electromagnetic waves. Convection involves the movement of heated particles, like air or water, transferring heat from one place to another.
What type of heat energy dose a telly give out radiation or convection or conduction?
Radiation, convection and conduction are not different types of energy, but different methods of conveying the energy. The heat energy from a television set will be conveyed mainly through conduction and convection, ie the casing will heat up through conduction and the air above the televison will become heated through convection. There will be heat transmitted by radiation, but this will quickly encounter air molecules which will then add to the convection effect.
How is air heated by conduction?
Air is heated by conduction when it comes into direct contact with a warmer surface, such as the ground or a heated object. The heat energy is transferred from the surface to the air molecules through direct contact, causing the air molecules to gain kinetic energy and move faster, increasing the air temperature.
When a hair dryer heats a balloon and the air inside it the balloon expands is radiation convection or conduction?
it is radiation but is also convection. thanks for the time to read it
How are the land air and water heated each day?
During the day, the land is heated mainly by the sun's radiation warming the surface. The air is heated through conduction from the warm surface of the Earth. Water is heated through a combination of direct solar radiation and convection currents transferring heat energy.
What happens to air heated by radiation?
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
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.
When the room becomes warm when the furnace is turned on which is the answer conduction convection radiation?
The answer is convection. Convection is the transfer of heat through the movement of fluids (liquids or gases), such as air becoming warm and rising as it is heated by the furnace, creating a convection current that warms the room.
An example of conduction convection and radiation working together?
a boiling pot because the stove radiates heat to warm the pot. the pot is touching the stove which is conduction. last when the pot is heated and boiling the steam is a form of convection. conduction could also be ice melting on a hot surface>

What is the air near the Earth's surface heated by?
The air near the Earth's surface is primarily heated by the Sun. Solar radiation warms the ground, which then heats the air through conduction and convection. Additionally, heat from human activities and natural processes can also contribute to heating the air near the Earth's surface.

How is earths surface heated and how does it affect the troposphere?
The Earth's surface is heated by the sun's radiation. The heated surface then warms the air in the troposphere through conduction and convection. This heating creates temperature gradients that drive atmospheric circulation patterns and weather systems within the troposphere.
Does an oven have conduction or convection?
Pizza in an oven recieves heat by radiation from the hot metal casing, and the burner, and by conduction from the air. Convection only heats fluids; so the air around the pizza (which is cooled by it) flows in convection currents, and interracts with hotter air. The pizza is heated faster because of convection heating taking place, but is not heated by it direction.
