pls ans fast the one who puts correct will be marked brainliest pls pls help fast

no wrong answer otherwise I will report​

Answer 1

Radiation and conduction is your answer

Answer 2

Answer:

CONDUCTION AND RADIATION

Explanation:

Heat transfer by conduction and convection works by particles colliding and transferring energy, as there are no particles in a vacuum heat transfer can only occur by radiation. This is because radiation involves electromagnetic waves, not particles, and is therefore able to transmit heat across a vacuum.
