- The vapor pressure of water at 10 °C is 1300 Pa. (a) What percentage of atmospheric pressure is this? Take atmospheric pressure to be 1.013 x 105 Pa. (b) What percentage of the total air pressure at 10 °C is due to water vapor when the relative humidity is 100%? (c) The vapor pressure of water at 30 °C is 4300 Pa. What is the relative humidity at this temperature if the partial pressure of water in the air has not changed from what it was at 10 °C when the relative humidity was 100%? (a) Percentage = Number i (b) Percentage = Number ₁ (c) Percentage = Number i Units Units Units <A basketball is pressurized to a gauge pressure of PG = 55 kPa when at the surface of a swimming pool. (Patm = 101 kPa). The ball is then submerged in the pool of water which has a density ρ = 1000 kg/m3. Assume the ball does not change in mass, temperature, or volume as it is submerged. Calculate the absolute pressure inside the basketball in kPa when it is at the surface. Write an equation for the pressure difference ΔP between the inside and outside of the ball when it is submerged a distance y below the surface of the water. Solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. At this depth the pressure inside the basketball is the same as the pressure outside the ball.What is the root-mean- Square Speed in mls of gas molecules with molar molecular weight 33 gimöl at a temperature of 87.29 °C?

The sides of the rods are insulated so there is no heat loss to the surroundings. What mass of ice is melted in 6.00 min by the heat conducted by the composite rod?A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
