If your car averages 22.07 miles per gallon, how many miles would you expect to drive on 13.243 gallons of gas?

A gas is compressed inside a cylinder. An average force of 12 N acts to move the piston 3 m. During the compression, 12 J of heat are conducted away from the gas. What is the change in internal energy of the gas?     Calculate answer to one decimal.

A gas is compressed inside a cylinder. An average force of 45 N acts to move the piston 4.7 m. During the compression, 85 J of heat are conducted away from the gas. What is the change in internal energy of the gas?     Calculate answer to one decimal.

The temperature at state A is 20.0ºC, that is 293 K. How many moles of ideal gas is there in the container? 1.00 atm = 1.00×105 Pa. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

For most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case.

A typical diving cylinder has 600 L of gas compressed into a 3-L volume. Which of the following statements is true regarding the gas? Its mass doesn’t change during compression. Its density increases during compression. Its volume decreases during compression. all of the above none of the above

Hi, could I get some help with this macro-connection physics problem involving moles and the Ideal Gas Law? The set up is: How many moles are there in a cubic meter of an ideal gas at 100 degree celsius (C) to 4 digits of precision with a pressure of 0.25 atm, assuming 1 atm = 101325 N/m2 with kB = 1.38e-23 J/K and NA = 6.022e23? Thank you.

A container of gas holds 1.04 moles of neon gas. If the volume of the container is 10.1 liters and the pressure inside is 2.4 atm, what is the temperature (in K) of the gas?

A sealed 12 m³ tank is filled with 6000 moles of ideal oxygen gas (doatomic) at an initial temperature of 270k The gas is heated to a final temperature of 340 k The atomic mass of oxygen is 16.0g/mol. The mass density of the oxygen gas in the SI units is closest to

A quantity of gas in a piston cylinder has a volume of 0.478 m3. If the gas is initially at room temperature (20°C) and is heated in an isobaric (constant-pressure) process, then what will be the temperature of the gas in degrees Celsius when it has expanded to a volume of 0.789 m3?
