Chapter 7, Problem 123FP

Interpretation Introduction

Interpretation:

The given statement by the James joule related to the first law of thermodynamic needs to be validated.

Concept introduction:

The potential energy of any object/person at some height is represented as follows:

$PE=mgh$

Here, m is mass, g is acceleration due to gravity and h is height.

The heat released or absorbed in a reaction can be calculated as follows:

$q=mC\Delta T$

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