.5 kJ of heat is applied to a 1012-g block of metal, the temperature of the metal increases by 11.4 °C. Calculate the specific heat capacity of the metal in J/g °C.

Interpretation Introduction

Interpretation:

The specific heat capacity of the metal in J/g C should be calculated.

Concept Introduction:

The specific heat is defined as the amount of heat per unit mass needed to raise the temperature by one degree Celsius.

It is mathematically represented as follows:

Q=msΔT

Here, Q is heat, m is mass, s is specific heat capacity and ΔT is change in temperature.

Explanation

Given Information:

The heat applied is 69.5 kJ, mass of metal block is 1012 g and the temperature of metal is increased by 11.4 C.

Calculation:

The specific heat capacity can be calculated using the following equation:

Q=msΔT

On rearranging,

s=QmΔT

On putting the values,

s=(69
