A lizard of mass 5.60 g is warming itself in the bright sunlight. It casts a shadow of 1.60 cm2 on a piece of paper held perpendicularly to the Sun’s rays. The intensity of sunlight at the top of the Earth's atmosphere is 1.40 × 103 W/m2, but only half of this energy penetrates the atmosphere and is absorbed by the lizard. The lizard has a specific heat of 4.20 J/(g·°C).Assuming that there is no heat loss by the lizard (to simplify), how long must the lizard lie in the Sun in order to raise its temperature by 1.50°C?

Given: mass of the Lizard m = 5.60 g area of the lizard shadow means lizards area A = 1.60 cm2 = 1.6…

Question

A lizard of mass 5.60 g is warming itself in the bright sunlight. It casts a shadow of 1.60 cm² on a piece of paper held perpendicularly to the Sun’s rays. The intensity of sunlight at the top of the Earth's atmosphere is 1.40 × 10³ W/m², but only half of this energy penetrates the atmosphere and is absorbed by the lizard. The lizard has a specific heat of 4.20 J/(g·°C).

Assuming that there is no heat loss by the lizard (to simplify), how long must the lizard lie in the Sun in order to raise its temperature by 1.50°C?
