Chapter 10, Problem 7A

(a)

Interpretation Introduction

Interpretation:

The term temperature depends on the amount of substance or not is to be stated.

Concept Introduction :

Matter is said to be anything that has the ability to occupy volume and has mass. Thermodynamics is related to the flow of heat. It tells about the feasibility of the reaction.

Answer to Problem 7A

Temperature does not depend on the amount of substance.

Explanation of Solution

The property that is not dependent over the amount of material that is being measured is known as intensive property. Temperature is an intensive property. It is identical for every part of system.

Therefore, temperature does not depend on the amount of substance.

(b)

Interpretation Introduction

Interpretation:

The term thermal energy depends on the amount of substance or not is to be stated.

Concept Introduction :

Matter is said to be anything that has the ability to occupy volume and has mass also. Thermodynamics is related to the flow of heat. It tells about the feasibility of the reaction.

Answer to Problem 7A

Thermal energy depends on the amount of substance.

Explanation of Solution

The property that is dependent over the amount of material that is being measured is known as extensive property.

If the amount of substance is high, the number of molecules will also be high, which means the thermal energy is also high. Thermal energy is an example of extensive property.

Therefore, thermal energy depends on the amount of substance.
