Heat Tranfers

Where is heat going?

How does heat move?

SummaryHeat is the flow of thermal energy and it moves from a place of warmer matter to colder matter. There are three different types of heat transfers which are conduction, convection, and radiation. Conduction usually moves through solids and is transfered by direct contact. Convection is a heat transfer though fluids. And lastly, radiation is a type of heat transfer that can warm something without physically touching it and travels through nothingness to heat the earth.

What is heat?

Heat is coming from a place of warmer matter and is going to a place of colder matter.

There are three different types of heat transfers - conduction, convection, and radiation.

Heat is the flow of thermal energy (the movement of particles) from a place of warmer matter to colder matter.

What is conduction?

What is convection?

What is radiation?

Convection is a type of heat transfer through fluids. A convection current is the continuous cycle of fluids rising, cooling, and sinking. Without heat transfers by convection we wouldn't have wind, ocean currents, or mountains.

Radiation is a type of heat transfer that can warm something without physically touching it. It involves no fluids or solids and heats the earth by traveling through empty space (nothingness).

Conduction is a type of heat transfer that requires two objects with different temperatures to be touching. It usually involves solids.

Examples:•burning your hand if it touches a hot stove•ice cooling down your hand•a mug with a hot drink in it warming up your hands

Examples:•boiling water•steaming cup of tea•hot air balloon

Examples:•camp fire•lightbulb•sunlight
