Summary Introduction

To determine:

The metal that uses least amount of heat energy during cooking out of the given metals.

Introduction:

Energy is the capacity to do work. There are many forms of energy like kinetic energy, potential energy, heat energy, and chemical energy.

Heat energy increases the temperature of the system as well as its surrounding. It is the kinetic energy flowing from the body at higher temperature to the body at lower temperature.

Thermal conductivity is the property of metal by which it conducts heat. Its value provides the information whether the metal is a good or bad conductor of heat.

Specific heat capacity is the amount of heat required to raise the temperature of $1\text{g}$ of substance by $1$ degree Celsius.

Specific heat of a substance is given by the expression,

$\text{Specific}\text{heat}\text{of}\text{substance}=\frac{\left(\text{Heat}\text{of}\text{the}\text{subsatance}\right)}{\left(\text{Mass}\text{of}\text{substance}\right)\left(\text{Temperature}\text{difference}\right)}$
