How many calories of heat are required to raise the temperature of 10 grams of iron from 100°c to 200°c? (question number7)

110 calories are required to raise the temperature.

-

Specific heat = calories / mass * (final temperature - initial temperature)

Insert known factors of the equation before rearranging to isolate the unknown (in this case, calories)

0.11 = calories / 10 * (200 - 100)
0.11 = calories / 10 * 100
0.11 * (10 * 100) = calories
0.11 * 1000 = calories
110 = calories
