The heat of the sun reaches us through radiation. The nuclear fusion process in the sun, which turns helium existing in the sun into a blazing ball of fire, generates heat. It is the earth’s main source of heat and light. Just enough heat is sent from the sun to support life on earth. The process of photosynthesis, which plants and other life-supporting organisms carry out, is also heated by the sun on Earth.

Heat Transfer of Sun

Conduction, convection, and radiation are the three modes of heat transport that are known to exist. Heat is transferred through conduction when molecules in the medium collide. Commonly seen in gases, liquids, and solids. According to conventional wisdom, the movement of the system’s fluids causes heat transfer. Commonly seen in fluids, such as liquids and gases.

  • Radiation is the process through which heat is transmitted across a medium through electromagnetic radiation.
  • We know that a vacuum exists in space and that electromagnetic radiation can travel through one.
  • Thus, radiation is evident in how the sun’s heat reaches the earth.
  • Since the sun rises in the morning and sets in the evening, it is also utilized to establish the time.

Summary:

Heat from the Sun Reaches us by?

Radiation is the transfer mode by which the sun’s heat reaches us. Heat is carried through a medium by the process of radiation in the form of electromagnetic radiation. Radiation is one of the modes of heat transfer which does not require any mode to transfer the energy. Unlike conduction and convection, radiation can be done in a vacuum.
