aring Suppose that 2.45 g of gaseous nitrogen, N2, is placed in a 2.15 L container The pressure is measured to be 475.0 mmHg What is the Celsius temperature of the gas? [Hint: Your first step should be solving the ideal gas equation for T.] ΜΕ ΑΣΦ ?

1. Which diagrams showing relationships between pressure, volume, and temperature below is/are incorrect for ideal gases? A B C KKKK V P T/P D PV

In an air-conditioned room at 21.0 ∘C, a spherical bubble had the diameter of 60.0 cm. When taken outside on a hot summer day, the bubble expanded to 61.0 cm in diameter. What was the temperature outside in degrees Celsius? Assume that the bubble is a perfect sphere and that the pressure and number of moles of air molecules remains the same.

The volume of an automobile tire is 2.5 × 10−2m3 . the pressure of the air in the tire is  2.7 atm and the temperature is 11C ◦ . what is is the mass of air in grams ? The mean molecular mass of air is 29g.                                     1 atm = 1.01  × 105 Pa ;    Calculate to 2 decimals.

2. The pressure inside a 4.00 L cylinder of gas is 1.808 atm. If the gas was comnpressed to a pressure of 440.0 kPa, what would its volume become? (Assume constant T). Note: 1 atm= 101.325 kPa

The average kinetic energy of the molecules in a gas sample depends only on the temperature T. R=8.314. What is the rms speed 02 molecules at 443 K? What is the rms speed of He atoms at 443 K?

(1) - The temperature is 21.3° C, atmospheric pressure is 755 mmHg and the volume of the gas bag is 981 mL. Convert each of these measurements to a set of units needed in the Ideal Gas law. Show all work! i) ii) temperature: pressure: volume:

A homeowner uses 4.00x10³ m³ of natural gas in a year to heat a home. Assume the gas is CH4 and that it behaves as a perfect gas. If the pressure is 1.00 atm and the temperature is 20.0°C, what is the mass of the gas used?
