2. (5 points) A piston head compresses a cylinder 10 cm long and 5.0 cm in diameter. The combustion chamber contains air and gasoline at 293 K and 1.0 atm. If the head is pushed in very quickly, compressing the mixture to half its original volume, how hot does the mixture become inside the chamber? (Assume that the mixture behaves like a ideal diatomic gas, the ignition temperature of gasoline is between 530 and 553K) 3. (5 points) An ice sheet forms on a lake. The air above the sheet is at -10°C, wherens the water is at 0°C. Assume that the heat of fusion of the water freezing on the lower surface is conducted through the sheet to the air above. How much time will it take to form a sheet of ice 10 cm thick? Thermal conductivity of ice is 2.25 W/mK
