You perform the following steps:
1. Heat up a balloon that contains 4 mol of helium gas from 293K to 353K....
a) The reason for performing step 2 very slowly is to keep the process reversible.
b) Since it is given that process 1 takes place in oven at 2 atm pressure, hence its a isobaric process AB and the volumes can be calculate using formula T1/V1 =T2/V2. V1 is the volume at T=293 and V2 at 353 respectively. putting V2= 0.5L we get V1=0.42L. Now the volume is reduced keeping the temprature constant BC at 353K. therefor using P1V1=P2V2 where V1=0.5L and V2=0.25L and P1=2atm. we get P2=4atm. now finally the pressure is reduced by keeping volume constant i.e. isochorically CD. therefore P1/T1=P2/T2 where P1=4atm and T1=353 and T2= 293 we get P2 = 3.32atm. hence the graph drawn is as shown below.

A cylinder contains 0.0100 mol of helium at 27.0 ?C. How much heat is needed to raise the temperature to 67.0 ?C while keeping the volume constant?(4.99) If instead the pressure of the helium is kept constant, how much heat is needed to raise the temperature from 27.0 ?C to 67.0 ?C?(8.31 J) If the gas is ideal, what is the change in its internal energy in part A? If the gas is ideal, what is the change in its...
Question 1.) Use the worked example above to help you solve this problem. A balloon contains 4.40 moles of a monatomic ideal gas. As energy is added to the system by heat (say, by absorption from the Sun), the volume increases by 25% at a constant temperature of 26.0°C. Find the work Wenv done by the gas in expanding the balloon, the thermal energy Q transferred to the gas, and the work W done on the gas. Wenv = ____J...
25. You’re at the zoo and have a big red 3.20 L helium balloon. The barometric pressure is 790.0 mm Hg. Then you hear the roar of a lion. Startled, you accidently release the balloon. It flies away. By the time it reaches the clouds the atmospheric pressure is only 0.300 atm. What is the new volume of the balloon? a) 6.20 L b) 11.1 L c) 1.06 L d) 8.43 L 26. A gas sample is held at constant...
