Answer:
90 °C
Explanation:
First, we must know the specific heat capacity of water, which is defined as the energy required to heat 1 gram of water by one degree Celsius. The specific heat capacity of water is 1 cal·g⁻¹°C⁻¹.
The equation we will use is Q = mcΔt, where Q is the heat energy, m is the mass, c is the specific heat capacity, and Δt is the temperature change. We will rearrange the equation to solve for Δt and substitute the values:
Δt = Q / (mc) = (90 kcal)(1000 cal/kcal) / (1 kg)(1000 g/kg)(1 cal·g⁻¹°C⁻¹) = 90 °C
Well, if you have a light bulb (turned on) n u put a little gulf ball in front of it it will make a shadow.
In this case the light bulb is the Sun and the gulf ball is the Moon.
So the Moon causes the shadow because it covers the light.
I really hope my explanation helps you out!
