Question

If the temperature of the Sun is doubled ; the rate
of energy per unit surface area received on Earth
will be increased by a factor of:​

Answer 1

Answer:

yes it is doubled ..thank you

Answer 2

For hot objects, the power radiated per unit area= p/a = eóT^4

This is called Stefan-Boltzmann Law.

Hence  P∝T4.

This means that the rate of energy received on Earth becomes 2^4=16 times when the temperature of Sun gets doubled.
