Chapter 14, Problem 8STP

To determine

To Choose: The correct option.

Answer to Problem 8STP

Option C

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.

Calculation:

From the graph, the volume of Gas B at temperature $100\text{K}$ is $200\text{mL}$ . Thus, the option (A) is incorrect.

From the graph, the volume of Gas B at temperature $400\text{K}$ is $400\text{mL}$ . Thus, option (B) is incorrect.

From the graph, the volume of Gas B at the temperature $400\text{K}$ is nearly $800\text{mL}$ . Thus the option (D) is incorrect.

From the graph, the volume of Gas B at the temperature $300\text{K}$ is nearly $600\text{mL}$ . Thus the option (C) is correct.

Conclusion:

Thus, the correct option is (C).
