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 ?

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

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
