Consider a balloon with volume v. it contains n moles of gas and has an internal pressure of p. the temperature of the gas is t. the balloon is placed in a freezer at temperature 0.75t. the freezer is pressurized at 1.25p. which of these could be the final volume of the balloon?

Given that the gas inside the balloon is an ideal gas, then the ideal gas equation can be used to describe the system. I think the correct answer from the choices listed above is option B. If the balloon is heatedto a temperature of 15.5T while it is placed under a high pressure of 15.5P, then the volume of the balloon stays the same since the change in temperature corresponds to same degree of change with pressure.

Consider a balloon with volume V. It contains n moles of gas and has an internal pressure of P. The temperature of the gas is T. The balloon is placed in a freezer at temperature 0.75T. The freezer is pressurized at 1.25P. Which of these could be the final volume of the balloon?

answer 0.60V

The balloon is removed from the freezer and returned to its initial conditions. It is then heated to a temperature of 2T at a pressure of 2P. How does the volume of the balloon change?

it does not change

If the number of moles of gas increases to 1.5n, what is the new volume if pressure and temperature are held constant?

1.5V

answers on ed I'm putting the last 3 because I was struggling on them as well :)

i would say b

explanation:

but i think i would need more information than that
