3. The pressure, temperature and volume of an ideal gas are given by the ideal gas law pV = nRT where n is the number of moles of the gas, R=8.314 J/(mol×K) is the gas %3D constant. The change of the temperature T with the time t is given by T =273+43Jt . The change of the volume V with time is given by V = 22– 2t0°. Determine the rate of change of the pressure of 1000 moles gas with time at t = 20s. ANS= 1Q99

Two containers of equal volume each hold samples of the same ideal gas. Container A has 2 times as many molecules as container B. If the gas pressure is the same in the two containers, find the ratio of the the absolute temperatures TA and TB ( i.e  TA / TB  ) . Calculate to 2 decimals.

If gas pressure (absolute value) for an ideal gas is held constant, the relationship between gas temperature and volume is direct inverse of the form y = mx + c O parabolic

1. Three moles of a monoatomic ideal gas are placed in a portable container with a volume of 4.10 x 10¬³ m3. The temperature of the gas is 165 °C. What is the average kinetic energy per molecule? sf60 s 60 ssfoc sf60 st ssf60

A balloon is filled with helium gas at atmospheric pressure (1 atm) until its volume is 800 m³. The helium gas is then transferred to cylinders that have a volume of 2.3 m³ at a pres- sure of 13.3 atm. Calculate the number of cylinders used. Assume that the temperature of the helium gas remains constant. (1 atm = 1.013 × 105 Pa).

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.

A fixed amount of a particular ideal gas at 20°C and a pressure of 1.75 × 105 Pa occupies a volume of 2.60 m3. If the volume is increased to 4.2 m³ and the temperature is raised to 27.0°C, what will be the new pressure (in Pa) of the gas? Pa

25. A movable circular lid rests on top of an a gas-filled a cylinder; the cylinder and lid have a radius of 12.0 cm; the lid has a weight of 800 N. Outside the cylinder is atmospheric pressure, 1.01 x 105 Pa. Inside the cylinder are 6.0 moles of argon gas. The gas temperature is 400 °K. What is the volume of the gas (in cubic meters)?
