The specific heat of a mystery substance that requires 79 joules of energy to heat 4.52 grams of substance from 23 degrees Celsius to 54 degrees Celsius is 0.56 J/g°C.
The specific heat capacity of a substance can be calculated using the following formula:
Q = mc∆T
Where;
c = Q/m∆T
c = 79 ÷ 4.52 × (54 - 23)
c = 79 ÷ 140.12
c = 0.56 J/g°C
Therefore, the specific heat of a mystery substance that requires 79 joules of energy to heat 4.52 grams of substance from 23 degrees Celsius to 54 degrees Celsius is 0.56 J/g°C.
