Answer #1

The specific heat tells us the amount of heat required to bring about a change in the temperature of the system/object.
We need to keep in mind the units mentioned in the question, since the specific heat takes grams and celsius in consideration, we have to change the value of our change in temperature to celsius scale.

DT = 161.78 - 49.64 °F 112. 14° Fluetoon Specific heat a 0.444 Jlg c. also DT (°F) - 9 x AF (°C) So DT (°C) = 5 x 112.14 beva
