Directions: Solve the following gas law problems. You MUST show your work on your paper (you can take a picture of your work on loose-leaf if you do not know how to do this on the computer and if you do not have a scanner. Submit the picture to the drop box, as well.) These are new problems that have never been assigned in any previous class. (3 points each) 1. The pressure of a gas in a 2.00 L container is 1.43 atm at a temperature of 18.7º C. What is the new pressure if the temperature remains constant and the volume decreases to 1.75 L? 2. What was the initial volume of a gas at 0.500 atm if its new pressure is 1.00 atm in a 10.0 L cylinder? Assume no change in temperature and no loss of gas during the transfer. 3. A 0.750-L container containing gas at a temperature of 27.3° C is transferred to a flask with a volume of 0.500-L. Assuming there is no change in pressure during or after the transfer, what is the temperature of the gas in the new flask? 4. The volume of a gas in an expandable container is 45.0 L at 44.3º C. If the pressure remains constant, what is the new volume when the temperature increases to 55.0º C? 5. At constant volume, the pressure of air in a container is 1.60 atm when the temperature is 25.0° C. What is the new pressure if the temperature is increased to 30.0° C? 6. A mixture of gases in a 4.5-L rigid-sided container is heated from a temperature of 28.5° C to 37.8° C. If the initial pressure was 1.12 atm, What is the new pressure? 7. What will be the temperature in Celsius of a gas sample having a volume of 3.20 L and a pressure of 1.32 atm if its original temperature was 22º C, its volume was 2.20 L, and its pressure was 2.50 atm? 8. What was the initial volume of a gas at 1.0 atm and having a temperature of 32.0º C if it was gets transferred to a 2.25-L container at a room temperature of 22.1º C and a pressure of 1.05 atm?

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
