Question

The specific heat capacity of wood 2.03joules /grams degrees Celsius.how much heat is needed to convert 550 grams of wood at 10.0 degrees Celsius to 35.0degrees Celsius ?

Answer 1

Step-by-step explanation:

Given parameters:

Specific heat capacity = 2.03J/g °C

Mass of wood = 550g

Initial temperature = 10°C

Final temperature = 35°C

Unknown:

Amount of heat = ?

Solution:

The quantity of heat supplied to a substance to effect a temperature change is given as;

H = m c Ф

here m is the mass

c is the specific heat capacity

Ф is the temperature change

The temperature change is the difference between the final and initial temperature.

Ф = Final temperature - Initial temperature = 35 - 10 = 25°C

Input the parameters:

H = 550 x 2.03 x 25 = 27912.5J
