Chapter 13, Problem 106A

Interpretation Introduction

Interpretation:

The value given by ideal gas law at high pressures and low temperatures is to be determined.

Concept introduction:

Kinetic − molecular theory can be applied to give the result.

Answer to Problem 106A

Higher pressure is calculated by ideal gas law at high pressures and low temperatures

Explanation of Solution

At high pressure, the molecules of gas come closer. Due to which force of attraction between the particles increases which decreases the force of collision on the walls of container. Hence, actual pressure is lower than the value of pressure given by ideal gas law.

At low temperature, kinetic energy of gas molecules will decrease which will lower the pressure on the walls of the container.

Conclusion

Higher pressure is calculated by ideal gas law at high pressures and low temperatures.
