A sample of copper absorbs 4.31E+1 kJ of heat, resulting in a temperature rise of 6.71E+1 °C. Determine the mass (in kg) of the copper sample if the specific heat capacity of copper is 0.385 J/g°C.

1.67 kg

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed= =   (1kJ=1000J)

m= mass of substance = ?

c = specific heat capacity =

Change in temperature ,

Putting in the values, we get:

  (1kg=1000g)

Thus the mass (in kg) of the copper sample is 1.67

the correct answer is boyle
