Chapter 14, Problem 7STP

To determine

To Choose: The correct option.

Answer to Problem 7STP

Option A

Explanation of Solution

Introduction:

Charles’s law states the volume is directly proportional to the temperature at constant pressure.

  $V\propto T$ .

Where,

• $T$ is temperature of gas.
• $V$ is volume of gas.

According to the given graph, Gas B has an increase in a volume less than that of an increase in the volume of Gas A with an increase in temperature.

Thus, option (B) is incorrect

According to the given graph, Gas C has an increase in a volume less than that of an increase in the volume of Gas A with an increase in temperature. Thus, option (C) is incorrect.

According to the given graph, Gas A has the greatest increase in volume than that of the increase in the volume of Gas B and Gas C.

Thus,the option (D) is incorrect.

According to the given graph, Gas A has the greatest increase in volume with increases in temperature. Therefore, the correct option is (A).

Conclusion:

Thus, the correct option is (A).
