- a. In the deep space between galaxies, the density of atoms is as low as 106 atoms/m³, and the temperature is a frigid 2.7 K. What is the pressure (in Pa)? 0.00000000000000003726 Pa b. What volume (in m³) is occupied by 5 mol of gas? m3 Enter an integer or decimal number more..] c. If this volume is a cube, what is the length of its sides in kilometers? kmarrow_forwardHi, could I get some help with this macro-connection physics problem involving moles and the Ideal Gas Law? The set up is: How many moles are there in a cubic meter of an ideal gas at 100 degree celsius (C) to 4 digits of precision with a pressure of 0.25 atm, assuming 1 atm = 101325 N/m2 with kB = 1.38e-23 J/K and NA = 6.022e23? Thank you.arrow_forward6.arrow_forward
- Q.5. One mole of oxygen gas is at a pressure of 6 atm and a temperature of27 °C. (a) If the gas is heated at constant volume until the pressure triples,what is the final temperature? (b) If the gas is heated until both the pressureand volume are doubled, what is the final temperature?arrow_forwardFigure I shows the P-V graph for a sample of a gas at 298 K. If this sample were heated to 312 K, this would be represented by a point 25. atm Figure 1 100 V/e 50 A At the top, left end of the line Off the line, above and to the right of it.

Calculate a numerical value for the internal energy U of this gas. Include units in your answer, using Sl units (m for meters, kg for kilograms, s for seconds, J for joules, K for kelvin, etc.). Write your answer as an exponential as described in the instructions.arrow_forward
- 2.40 moles of an ideal gas is initially at 40.0 oC and 1.35 atm. a) What is its volume under these conditions?b) If it is then compressed to one third of its initial volume and its pressure increases to 2.0 atm, what, in Centigrade degrees, will be its temperature?arrow_forwardProblem 3. The viral coefficients of a gas at 20 °C and 11.5 bar are B = -138 cm³ mol¹ and C=7222 cmº mol². Calculate the V (molar volume) Z (compressibility factor) of the gas. Use the equation below (R = 83.14 cm³ bar mol-¹ K-¹). PV 2 = ² = (1 + = + =) Z RTarrow_forwardThe temperature at state A is 20.0ºC, that is 293 K. How many moles of ideal gas is there in the container? 1.00 atm = 1.00×105 Pa. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given inarrow_forward
- 1.50 moles of a monatomic ideal gas goes isothermally from state 1 to state 2. P1 = 2.8×105 Pa, V1 = 88 m3, and P2 = 6.6×105 Pa. What is the volume in state 2, in m3? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.arrow_forwardA dilute gas expands quasi-statically from 0.3 to 5 L at a constant temperature of 280 K. Follow the steps below to calculate the number of molecules in the gas, with some additional information provided. Hint For an isothermal expansion, does the pressure of the gas remain constant? Hint for (a) No, it does not remain constant. Yes, it remains constant. Answer depends on additional information not given. Correct If the pressure does not remain constant, we cannot calculate the whole amount of work with W=PΔVW=PΔV. Instead, we need to start out with the infinitesimal work done for infinitesimal volume change (dW=PdVdW=PdV) and integrate over the interval of volume change to calculate the total work done (this is also same as the area under the curve in P-V diagram). Fill in the blank in the setup for the integral below, in terms of VV (volume), NN (number of molecules), TT (temperature), and kk (Boltzmann constant) and other numerical constants. Hint for (b) Total work…arrow_forwardThe temperature at state A is 20ºC, that is 293 K, what is the temperature at state D, in Kevin?
