Question

Radiant heat can easily pass through_______ .

Answer 1

Hint: Radiation does not need a medium to transfer heat unlike conduction, convection. In the radiation process heat transmits in the form of electromagnetic radiation.
Here the heat transmits from the sun to the earth in this radiation process. Hence read the following statement to answer the above statement.

Complete answer:
The radiation travels in the straight lines like light. Radiation does not need a medium to transfer heat unlike conduction, convection.
In the radiation process heat transmits in the form of electromagnetic radiation. Here the heat transmits from the sun to the earth in this radiation process.
Radiation is used for both as a process and energy. It can travel in vacuum. Thermal radiation is the only radiation that can be at equilibrium.
Thermal radiation undergoes reflection, refraction, total internal reflection. Thermal energy diffusion inside one material or between materials in contact is called thermal conductivity.
As the kinetic energy then the temperature will increase in an object.
This results in the collisions between molecules distributions.
Heat energy is radiated from the sun at the speed of light. The energy when reached on earth, some of that energy will be transferred to the gases in our atmosphere.
Radiant heat can pass easily through vacuum and air.
Here radiant energy does not require any medium to transfer heat from hot objects to cold objects.
Radiant heat can easily pass-through air as heat can pass very easily in vacuum as well as air.

Note: For heat exchangers, the thermal conductors are very useful and they allow heat to be exchanged between liquids and it’s mixing them.
The heat is produced from the thermal conduction for the transfer. A substance is said to be a good conductor of heat if the value of coefficient of thermal conductivity is large.
