Volume of Balloon Unchanged When Pressure Doubled & Temp Changes

    Balloon Pressure
AI Thread Summary
When pressure on a balloon is doubled, the volume will change unless the temperature is adjusted accordingly. According to the ideal gas law, if the volume remains constant, an increase in pressure requires a proportional increase in temperature. The discussion highlights confusion about the assumption that the balloon's volume can remain unchanged despite changes in pressure and temperature. Participants emphasize that higher temperatures lead to more energetic gas particles, which affects volume. Ultimately, to maintain constant volume while doubling pressure, the temperature must also increase significantly.

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 Celcius) 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.
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
