FAQs

How do you calculate the equilibrium temperature of a planet? The equilibrium temperature of a planet can be estimated using the Stefan-Boltzmann law and the planet’s distance from its star, the star’s luminosity, and the planet’s albedo (reflectivity).

What is the thermal equilibrium of a planet? Thermal equilibrium refers to a state where the rate of energy absorption by a planet from its star is equal to the rate of energy radiated by the planet back into space.

What is Earth’s equilibrium temperature? Earth’s equilibrium temperature, considering its actual distance from the Sun and its properties, is approximately 255 Kelvin (-18°C or 0°F). This is significantly colder than its actual average surface temperature due to the greenhouse effect.

Why is Earth not in thermal equilibrium? Earth is not in thermal equilibrium because of the greenhouse effect, which traps heat in the atmosphere and raises the planet’s temperature above its equilibrium temperature.

What increases a planet’s equilibrium temperature? A planet’s equilibrium temperature increases with a higher star luminosity, a smaller distance from the star, and a lower albedo (higher absorption of incoming radiation).

What is the equilibrium temperature of Jupiter? Jupiter’s equilibrium temperature is approximately 120 Kelvin (-153°C or -244°F), assuming it receives the same amount of solar radiation as Earth.

What is the equilibrium temperature of the Earth without an atmosphere? Without an atmosphere, Earth’s equilibrium temperature would be much lower, around 255 Kelvin (-18°C or 0°F).

Does equilibrium mean the same temperature? No, equilibrium does not necessarily mean the same temperature. It means a balance between energy absorbed and energy radiated, which may result in different temperatures in different regions.

Does temperature have to be constant at equilibrium? No, temperature does not have to be constant at equilibrium. It depends on the specific conditions and factors influencing energy exchange.
