Chapter U5.4, Problem 1E

Interpretation Introduction

Interpretation:

The reason due to which large amount of energy is required to heat large sample of cold water as compared to small sample needs to be explained.

Concept Introduction :

The heat requiredper unit mass of a substanceto increase the temperature by one degree Celsius, is called specific heat.

Answer to Problem 1E

Large sample has more particles and larger mass thus, it requires more heat.

Explanation of Solution

The greater number of particles present in any substance requires more energy to heat up as compared to the substance having a smaller number of particles.

Because the larger sample has more particles or have larger mass thus, it takes more energy to increase the average kinetic energy of that sample by the same amount as the smaller sample.

Thus, large sample has more particles and larger mass thus, it requires more heat.
