How much energy is required to raise the temperature of 2kg of iron from 20 C to 23 C?
(Explanation): remember to convert the 2kg to grams, then multiply in this equation Q=(2000)(0.45)(3) to get Q=2700J
What is the specific heat of an unknown substance if 2000J of energy are required to raise the temperature of 4 grams of the substance 5 degrees celsius?
Just use the definition of specific heat. Use the following formula: (energy) = (mass) x (temperature difference) x (specific heat) Replace the amounts you know, and solve for the one you don't - in this case, the specific heat.
