A container contains 0.650 grams of He gas in a volume of 17.5 liter. If 0.260 g of He is remove a constant P and T, what will be the new volume?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation PV = 8.31T, where P is measured in kilopascals, V in liters, and T in kelvins. Use differentials to find the approximate change in the pressure if the volume increases from 10 L to 10.6 L and the temperature decreases from 335 K to 330 K. (Note whether the change is positive or negative in your answer. I Round your answer to ti decimal places.

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.

The Table shown gives experimental values of the pressure P of a given mass of gas corresponding to various values of the volume V. According to thermodynamic principles, a relationship having the form PVk = C, where k and C are constants, should exist between the variables. Use the natural log (In) and linear regression to solve the following. 1) Find the value of k. a) 0.74 b) 0.86 c) 0.98 d) 1.33 2) Find the value of C. a) 812 b) 765 c) 880 d) 947 3) Estimate P when V = 100.0 in3 a) 18.9 b) 30.8 c) 24.7 d) 49.5 TABLE V(in3) 54.3 61.8 72.4 88.7 118.6 244.9 P(lb/in?) 61.2 49.5 36.6 28.4 19.2 20.1 Write only the letter corresponding to the correct answer.

n = 3.9 moles of an ideal gas are pumped into a chamber of volume V = 0.135 m3   Part (a)  The initial pressure of the gas is 1 atm. What is the initial temperature (in K) of the gas?        Part (b)  The pressure of the gas is increased to 10 atm. Now what is the temperature (in K) of the gas

Consider a pressure versus volume graph, where the different curves represent different processes done on a gas. Starting at the origin to point 1, the pressure and volume are increased to 2913 Pa and 4.25 m³, respectively. From 1 to 2, the gas expands at constant pressure to a volume of 7.25 m³. From 2 to 3, the pressure rises to 4082 Pa. Finally, from 3 to 4, the gas expands again to 10.85 m³. Rank the curves from the most positive to the most negative amount of work done on the gas. Pressure (Pa) 0 1 3 2 Volume (m³) What is the total work done on the gas? 4 Wo-4 = Most positive work Incorrect 29624.325 23 0 → 1 1 → 2 3→ 4 Most negative work Answer Bank
