Answer .
A) 1,2,3
EXPLANATION =>
1. HEAT IS A FORM OF ENERGY.
yes , heat is a form of energy. As energy is neither be created nor be destroyed. it can be transferred from one form to another.
and heat is a form of energy it transferred from one system to another system.
as I know according to 2 nd law if thermodynamics heat transferred from cold system to hot system.
2. HEAT CAN REFLECT BY MIRROR .
Heat can be reflected by a mirror .As we know reflection take place when light fall on a mirror . so it mean heat is also a type of radiation . it is interesting actually ,it is truth heat is a type of radiation (infra-red radiation ) but our eyes can't not visible them due to its wavelength.
So it's obvious that the mirror will reflect the infrared wave but the reflectivity and how much is absorbed is different in this case
3. Heat is a electromagnet radiation.
As I told u in upper point heat is a infra -red radiation .so offcures it will be electromagnetic radiation beacuse infra -red is a electromagnet radiation.
eg electromagnet radiation involved.
Radio Waves.
TV waves.
Radar waves.
Heat (infrared radiation). ********
Light.
Ultraviolet Light (This is what causes Sunburns)
X-rays (Just like the kind you get at the doctor's office)
4. HEAT CAN'T PASS THROUGH VACCUM .
ACTUALLY heat pass through VACCUM, for more clearness I give a example .
as u know heat is a infrared radiation and The Sun (and anything warm) is constantly emitting infrared, and the Earth absorbs it and turns the energy into atomic and molecular motion, and we all know in space there is VACCUM mean heat is pass through VACCUM .but it can't conduct through VACCUM. because that requires molecules to move to carry the thermal energy. and VACCUM don't any molecules.
