Homework Help Overview

The discussion revolves around a gas law problem involving a balloon filled with gas at a specific volume, pressure, and temperature. The original poster questions how the temperature must change if the pressure is doubled while maintaining the same volume of the balloon.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between pressure, volume, and temperature as described by the ideal gas law. There are questions about the implications of the problem statement regarding volume stability amidst changing pressure and temperature.

Discussion Status

Participants are actively questioning the assumptions made by the original poster regarding the constancy of volume. Some have reiterated the idea that volume typically changes with pressure, while others seek clarification on the implications of the problem statement.

Contextual Notes

There is a focus on the ideal gas law and its implications, with some participants noting the need for clarity on the conditions under which volume remains unchanged. The discussion reflects a mix of interpretations regarding the problem's constraints.

A balloon is filled with a gas to a certain volume at a certain pressure at 22.0 degrees Celsius. If the pressure exerted on the balloon is doubled. explain what must the temperature ( in degrees celsius) be so that the volume of the balloon doesn't change.

If the temperature changes, the volume of the balloon will also change. Higher temperature,more energetic therefore more particle collisions, vice versa. So how can the temperature change but the volume of the balloon does not change( according to the questions)? Thanks!

What makes you think that the balloons volume does not change? The volume of the balloon will change as the pressure does.
 
I moved the thread to our homework section.

The pressure inside and the pressure outside both increase.

What do the words in the problem statement "so that the volume of the balloon doesn't change." mean to you?

Please write down the equation for the ideal gas law. From this equation, if V is constant, what does the temperature have to do if the pressure doubles?

I thought that OP was under the assumption that the volume cannot change. Apologies.
