Effects of Increasing Temperature on Ideal Gas

Click For Summary
Increasing the temperature of an ideal gas leads to an increase in the speed of its molecules, which is directly related to the energy of the gas. This aligns with the principles of Kinetic-Molecular Theory, where temperature is a measure of the average kinetic energy of gas particles. While other effects, such as increased pressure and volume, may occur, the primary factor is the increase in molecular speed. The discussion emphasizes that choice C is the most accurate response to the homework question. Understanding these relationships is crucial for grasping the behavior of gases under varying temperature conditions.

Homework Statement


If you increase the temperature of an ideal gas, then
a. the average distance a molecule travels between collisions must increase
b. the pressure must increase
c. the speed of its molecules must increase
d. the average time between collisions of its molecule must increase
e. the volume must increase



Homework Equations





The Attempt at a Solution


I think the correct selection is choice C because while the other selections are possible only the energy is solely related to the temperature?

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
