radiation
Infrared radiation does not require matter to transfer thermal energy. It can travel through vacuum, such as outer space, and is responsible for the heat we feel from the sun.
The transfer of thermal energy without matter is called radiation. Radiation is the process by which heat is transferred through electromagnetic waves, such as light or infrared radiation, without the need for a material medium. Examples include feeling the warmth of the sun on your skin or using a heat lamp to keep food warm.
True. Transfer of thermal energy by radiation does not require matter because it occurs through electromagnetic waves, such as infrared radiation, which can travel through vacuum where there is no matter. This form of energy transfer is how heat from the sun reaches Earth.
No, the movement of matter requires energy transfer. Energy is needed to overcome any resistance to movement, such as friction or inertia. Without energy transfer, matter would remain stationary or at rest.
The ability to transfer thermal energy from one area to another is called thermal conductivity. It is a physical property of matter that quantifies how well a material can conduct heat. Materials with high thermal conductivity can transfer heat efficiently, while materials with low thermal conductivity are poor heat conductors.
There are three ways to transfer heat energy (thermal energy); convection involves transferring matter, the other two methods (conduction, radiation) don't.

Everything, all matter within existence is subject to the transfer of thermal energy. Thermodynamics help us to understand how matter will behave when undergoing a change in thermal energy.
Radiation is the form of thermal transfer that does not require matter. It occurs through electromagnetic waves, such as light or infrared radiation, traveling through space and transferring heat energy. This process can happen even in a vacuum where there is no physical medium for heat transfer.
This mode of thrermal energy transfer is called CNVECTION.
