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
olga2289 [7]

Answer: 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=m\times c\times \Delta T

Q = Heat absorbed=4.31\times 10^1kJ = 43100J   (1kJ=1000J)

m= mass of substance = ?

c = specific heat capacity = 0.385J/g^0C

Change in temperature ,\Delta T=T_f-T_i=6.71\times 10^1^0C=67.1^0C

Putting in the values, we get:

43100J=m\times 0.385J/g^0C\times 67.1^0C

m=1670g=1.67kg   (1kg=1000g)

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