Question

How much heat does it take to raise 100g of aluminum (c= .9 J/gC) from 12.5C to 31C?

Answer 1

Answer:

When two substances having different temperatures are introduced or kept together, heat energy, Q, flows from a substance at higher temperature to a substance at lower temperature. Also, heat continues to be transferred until their temperatures are equalized, at which point the substances are in thermal equilibrium. In a closed system, the amount of energy lost is equal to but opposite the amount of energy gained.
