Specific Heat- The number of calories required to raise the temperature of 1 gram of a substance 1°C, or the number of BTU's per pound per degree F

Five Important Facts: Formula: Q=mc(delta)t
 * With a known specific heat being water, most specific heat capacities are found by combing a substance with another.
 * Water has high specific heat
 * The specific heat of water is 4.2 Joules per gram degree celcius 1 carlories per gram degree celcius
 * A material with a high specific heat capacity has a high capacity for storing heat energy
 * Water's specific heat it high because its more dense, and the hydrogen bonds are keeping the molecules from moving to much and to easily.

Problems: 1.) A 500 g piece of iron increases its temperature 7 C when heat energy is added. How much heat energy produced this change in temperature?

Answer: Q= mc (delta) t =500(0.11)(7) ==385 calories=

2.) A 1500 g piece of carbon increased its temperature by 10 C. How much heat energy was added? Q= mc(delta)t

(1500)(10)(0.17) (delta) t
=10 C= 2,550 Calories= 3.) 200 Grams of water decreased from 100 to 80 C. How much heat energy was lost? Q=mc(delta)t =(200) (1)(-20) ==-4000 calories=
