Stan Moneymaker needs 15 gallons of gasoline to top off his automobile’s gas tank. If he drives an extra eight miles (round trip) to a gas station on the outskirts of town, Stan can save $0.10 per gallon on the price of gasoline. Suppose gasoline costs $3.90 per gallon and Stan’s car gets 25 mpg for intown driving. Should Stan make the trip to get less expensive gasoline? Each mile that Stan drives creates one pound of carbon dioxide. Each pound of CO2 has a cost impact of $0.02 on the environment. What other factors (cost and otherwise) should Stan consider in his decision-making?

- Atmospheric pressure on Earth at its surface is 101 KPa (101 kilopascals or 101,000 N/m2). Which of these statements is true? If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will still be more than 1010 (10 billion) atoms per cm3 in the container. If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will be fewer than 100 atoms per m3 in the container. When we reduce the pressure in the container while keeping the temperature constant, the number of atoms per m3 must stay constant. At 1 atmosphere, the number of atoms/m3 in air at room temperature is about 109, one billion atoms.arrow_forwardAtmospheric pressure on Earth at its surface is 101 KPa (101 kilopascals or 101,000 N/m2).

The trip took about 22 days, and the fish consumed energy at a rate of 2.0 W for each kilogram of body mass. About 80% of this energy is released by burning fat and the other 20% by burning protein.

- How did it become like this?arrow_forwardHow can you apply gas laws in everyday life?arrow_forwardThe recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be?
