Question

What does the specific heat for a substance indicate? A. the heat released when 1 gram of the substance burns B. the amount of heat required to increase the temperature of 1 gram by 1oC C. the amount of heat required to increase the temperature of 100 grams by 1oC D. the amount of heat required to increase the temperature of 1 gram by 100oC E. the heat released when 100 grams of the substance burns

Answer 1

B. the amount of heat required to increase the temperature of 1 gram by 1oC

Answer 2

Answer:

B. the amount of heat required to increase the temperature of 1 gram by 1°C

Explanation:

The heat required by a substance having mass m to raise the temperature of it by ΔT.

Q = m c ΔT

where c is the specific heat of the substance.

$c = \frac{Q}{m\Delta T}$

Specific heat for a substance is the amount of heat required to increase the temperature of 1 gram by 1°C.

For example, the specific heat capacity of water is 4.186 J/g°C. This means 4.186 J is required to raise the temperature of 1 g of water by 1°C.
