Chapter 7.10, Problem 7.30P

Interpretation Introduction

Interpretation:

The amount of energy released when 2.00g of water is cooled from $55°\text{C}$ to $12°\text{C}$ is to be determined in calories or kilocalories.

Concept introduction:

The specific heat is calculated using the following formula:

  $\text{specific heat=}\frac{\text{Heat}}{\text{Mass×ΔT}}\text{=}\frac{\text{cal or J}}{\text{g}\text{.°C}}$

Or,

  $Q=m\times c\times \Delta T$

Here, Q is heat, m is mass, c is specific heat capacity and $\Delta T$ is change in temperature.
