10 g of dry ice (solid CO 2 ) is placed in a 10,000 cm 3 container, then all the air is quickly pumped out and the container sealed. The container is warmed to 0°C, a temperature at which CO 2 is a gas. a. What is the gas pressure? Give your answer in atm. The gas then undergoes an isothermal compression until the pressure is 3.0 atm, immediately followed by an isobaric compression until the volume is 1000 cm 3 . b. What is the final temperature of the gas? c. Show the process on a pV diagram.

a)A gas occupies an 8.00 mL flexible-walled container. The pressure is doubled, the absolute temperature is quadrupled, and 15% of the gas leaks out. What is the new volume?
b) A sample of neon has a volume of 0.730 dm3 at a temperature of 21.0 °C. and pressure of 102.5 kPa. If the density of neon is 0.900 g/dm3 at 0 °C and 101.3 kPa, what is the mass of the sample?
C) the radius of a copper bar is 4mm. What force is required to stretch the rod by 20% of its length assuming that the elastic limit is not exceeded? Y= 12×10^10N/m2
2. How much heat is needed to convert 1 kg of ice at -10℃ to steam at 100℃? Remember ice and water do not have the same specific heat.
a.) An ideal gas is in a sealed container. By what factor does the gas temperature change if the volume is halved and the pressure is tripled?
b.) An ideal gas is in a sealed container. By what factor does the gas temperature change if the volume is doubled and the pressure is tripled?
c.) If you have two jars containing the same amount, n1=n2, and type of gas (for example, oxygen) and they are at the same temperature, T, what can you say about their pressure if the first jar has four times the volume of the second, V1 = 4V2? Hint: use pV=nRT
