1
Conduction
The transfer of thermal energy from hot objects to cooler objects by direct contact, with no movement of material.
New cards
2
Convection
The transfer of thermal energy by the movement of molecules in air or liquid from one place to another.
New cards
3
Thermal conductor
A material that allows thermal energy to flow easily through it.
New cards
4
Thermal insulator
A material that prevents or slows down the transfer of thermal energy.
New cards
5
Convection current
The current or flow of air or liquid that results from the transfer of thermal energy through convection.
New cards
6
Kinetic energy
The energy possessed by particles due to their motion; higher temperature corresponds to higher kinetic energy.
New cards
7
Thermal energy
The total kinetic energy of the particles in a substance, relating to its temperature.
New cards
8
Heating by conduction
Involves the transfer of thermal energy between two objects in direct contact with each other.
New cards
9
Heating by convection
Involves the movement of warmer, less dense particles rising and cooler, denser particles sinking.
New cards
10
Expansion due to heating
The increase in size of a substance when its particles gain thermal energy and move more vigorously.
New cards
11

Thermal expansion

The property of matter to change its volume in response to a change in temperature.

New cards
12

Heat transfer

The process of thermal energy moving from a warmer object to a cooler one through conduction, convection, or radiation.

New cards
13

Radiation

The transfer of thermal energy through electromagnetic waves without the need for a medium.

New cards
14

Phase change

The transition of matter from one state (solid, liquid, gas) to another due to changes in temperature or pressure.

New cards
15

Thermal equilibrium

The state in which two objects in thermal contact reach the same temperature and no heat flows between them.

New cards
16

Specific heat capacity

The amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius.

New cards
17

Latent heat

The heat energy absorbed or released by a substance during a phase change without a change in temperature.

New cards
18

Thermal conductivity

A measure of a material's ability to conduct heat.

New cards
19

Insulation

The material or method used to reduce the rate of heat transfer.

New cards
20

Heat capacity

The amount of heat energy needed to increase the temperature of an object by a certain amount.
