You're inflating tires on your bike with a manual pump. The volume inside the pump is initially .16 m^3 with a pressure of 2 atm. If you push down on the piston and reduce the volume inside of .07 m^3, what is the new pressure inside the pump? Assume the temperature stays constant.
A U-shaped tube is open to the atmosphere on both ends. Water is poured into the tube, followed by gasoline, which floats on the water because it is less dense than water. The density of water is 1000 kg/m³ and the density of the gasoline is 680 kg/m³. If h₁ = 12.5 cm, what is h2, in cm? 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. h₂ P₂
I put air in the tires of my car during the summer, while it was 28.8 °C outside (about 83.8 °F). My tires say to fill them to a pressure of 203,000 Pa. Boltzmann's constant is 1.38 * 10 ^ - 23 * J / K A) If my tires have a volume of 0.0100 m³, how many air molecules are in the tire? N = molecules B) These tires go all summer without losing any air, however come fall the temperature drops down to 8.65 °C (about 47.6 °F). Assuming the volume doesn't change (because it doesn't) what is the new pressure in my tires? P=
