Write this down in your notebook and fill out the FIRST TWO ROWS OF THE IFE TABLE ONLY!

1) There is an empty 1.00 L soda bottle indoors at 1.2 atm of pressure and a temperature of 22°C (295 K). When taken outside, the plastic expands and now has 1.03 L of volume; the temperature rises to 350 K. What is the new pressure inside the soda bottle?

Select ALL correct answers (there are more than one)

• volume will increase, so pressure will decrease

• volume will increase, so pressure will increase

• temperature will increase, so pressure will decrease

• temperature will increase, so pressure will increase

When taken outside, the plastic expands and now has 1.03 L of volume; the temperature rises to 350 K. What is the new pressure inside the soda bottle? Let's add the info from the last slide to our IFE table in the "Effect" row and then solve our equation. You will type in your answer on the next slide; have your calculation ready!

Draw an IFE table on your whiteboard with your partner and fill it in.

2) Aerosol cans are prominently labeled with a warning such as “Do not incinerate this container when empty.” Assume that you did not notice this warning and tossed the “empty” aerosol can (0.025 mol if gas in it, initially at 25°C [298 K] and 1.5 atm internal pressure) into a fire at 750°C [1023 K]. 0.005 mol of gas leaked out of the container just before it hit the fire. What would be the pressure inside the can if it did not explode nor change volume?

3) A 1.00 mol sample of gas is in a .00500 L syringe at 2.00 atm. 2.50 mol of gas is put into the syringe; the syringe then expands to .00600 L. What is the pressure inside the syringe now?
