Answer:
THE SPECIFIC HEAT CAPACITY IS 4.44 J/G C
Explanation:
Heat energy = 20000 J
Mass = 100 g
Change in temperature = 145 C - 100 C = 45 C
Specific heat capacity = unknown
In calculating the specific heat capacity, we use the formula:
Heat = mass * specific heat capacity * change in temperature
Re-arranging the formula by making the specific heat capacity the subject of the equation, we have:
Specific heat capacity = Heat / mass * change in temperature
Specific heat capacity = 20000 J / 100 g * 45 C
Specific heat = 20000 / 4500
Specific heat = 4.44 J/g C
The specific heat capacity of the substance is therefore 4.44 J/g C
