Answer:
When a candle burns, the chemical energy in the candle changes to light energy and heat energy.<em> (C)</em>
Explanation:
Did you ever light a candle and have sound or electricity come out of it ? ?
Answer:
The outer core is a liquid
Explanation:
The outer core is a fluid composed of iron and nickel
In order to calculate the amount of energy required, we must first check the latent heat of vaporization of water from literature. The latent heat of vaporization of any substance is the amount of energy required per unit mass to convert that substance from a solid to a liquid. For water this is 2,260 J/g. We now use the formula:
Energy = mass * latent heat
Q = 50 * 2,260
Q = 113,000 J
113,000 Joules of heat energy are required.
