140 moles of a gas which has y = 1.31 expands from Vi = 0.5m³ to = 1.8m³ following the relation P(V) = 2.0 × 10³ Pa m³ / +1 +1.2 x 105. Pa. m³ V (2)

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

When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = πr²p. piston head V x The work done by the gas when the volume expands from volume V₁ to volume V2 is as follows. 1 W = dv In a steam engine the pressure and volume of steam satisfy the equation PV1.4 = k, where k is a constant. (This is true for adiabatic expansion, that is, expansion in which there is no heat transfer between the cylinder and its surroundings.) Calculate the work done by the engine during a cycle when the steam starts at a pressure of 180 lb/in² and a volume of 500 in³ and expands to a volume of 700 in³. (Round your answer to two decimal places.) W = X ft-lb

A sealed 99 m3 tank is filled with 6000 moles of ideal oxygen gas (diatomic) at an initial temperature of 270 K. The gas is heated to a final temperature of 320 K. The atomic mass of oxygen is 16.0 g/mol. The mass density of the oxygen gas, in Sl units, is closest to:
