thermal energy and heat

How is heat transferred.

Heat is transferred from warmer objects to cooler objects by 3 methods. The 3 methods are conduction, convection, and radiation.

key questions

what determines the temperature of an object

temperature is the measure of the average kinetic energy of an objects particles.

what is thermal energy

thermal energy is the total energy of all an objects particles.

vocabulary

Celsius scale: A heat measurement form where the freezing point is at 0 degrees and the boiling point is at 100 degrees

Fahrenheit: a heat measurement form that most countries don't use.

Kelvin scale: a heat measurement form where absolute zero is 0 degrees.

Temperature: A measure of the average kinetic energy of the particles in an object.

Absolute zero: the lowest temperature possible

Heat: The transfer of thermal energy from a warmer object to a cooler object.

hurricanes

Hurricanes are formed when very warm moist air rises quickly. this creates an area of lower air pressure below. As the air rises, water vapor in the air condenses, and releases a huge amount of thermal energy, which causes swirling winds which continue to feed the storm.

heat forms

Convection: A heat transfer that occurs only in fluids such as water and air.

Radiation: The transfer of energy by electromagnetic waves.

Conduction: The transfer of heat between one particle of matter to another within the same object or between two objects.

This is the difference between Celsius and Fahrenheit

That's what happens when particles heat up

Heat transfers from warm to cool objects

extra facts

1: Thermal energy is measured in joules

2: Thermal energy is difficult to transfer into other forms of energy

3: Objects cannot contain heat, they can only contain thermal energy

4: To transform thermal energy to other forms of energy, a machine is needed

5: the amount of thermal energy is not dependent on the amount of work
