Question

Which of the following explains the process of radiation?

when heat gets transferred through objects that are touching
when the measurement of heat in the atmosphere goes down
when heat gets transferred through electromagnetic waves that move through
space
when heat gets transferred through a liquid or a gas

Answer 1

RADIATION IS THE PROCESS WHERE HEAT IS TRANSFERRED THROUGH ELECTROMAGNETIC WAVES THAT MOVE THROUGH SPACE.

Step-by-step explanation:

Radiation is the transfer of energy in the form of waves through space or a material medium. It involves the emission of energy through electromagnetic waves such as radio waves, x-rays, gamma rays. Also, particles such as electrons, protons and neutrons are regarded as radiations when they travel at high velocities. Radiation are categorized into two; ionizing and non-ionizing radiations depending on the energy the matter carries. In ionizing radiation, matters carry sufficient energy which can be used to ionize atoms or molecules and even break chemical bonds; charged particles or ions are therefore produced in matter and such radiations include gamma rays, x-rays, alpha particles, beta particles.
