Can carbon dioxide be liquefied at room temperature ( 20ºC )? If so, how? If not, why not? (See Figure.) Figure: The phase diagram for carbon dioxide. The axes are nonlinear, and the graph is not to scale. Dry ice is solid carbon dioxide and has a sublimation temperature of – 78.5ºC .

The image shows the example of finding the number of vacancies in 1 cubic meter of copper (Cu) at 1000 degrees celcius (1273 k) considering the image data. Replicating the problem in the image, calculate the number of vacancies but at room temperature.Explain why there is such a difference in the number of vacancies at both temperatures.

Constants Periodic Table Assume all temperatures to be exact, and neglect significant figures for small changes in dimension. On a warm day (92 °F), an air-filled balloon occupies a volume of 0.300 m³ and has a pressure of 24.0 lb/in?. Part A If the balloon is cooled to 32 °F in a refrigerator while its pressure is reduced to 14.7 lb/in?, what is the volume of the air in the container?

Learning Goal: To understand the ideal gas law and be able to apply it to a wide variety of situations. The absolute temperature T, volume V, and pressure p of a gas sample are related by the ideal gas law, which states that PV = nRT Here n is the number of moles in the gas sample and R is a gas constant that applies to all gases. This empirical law describes gases well only if they are sufficiently dilute and at a sufficiently high temperature that they are not on the verge of condensing. In applying the ideal gas law, p must be the absolute pressure, measured with respect to vacuum and not with respect to atmospheric pressure, and I must be the absolute temperature, measured in kelvins (that is, with respect to absolute zero, defined throughout this tutorial as -273°C). If p is in pascals and V is in cubic meters, use R = 8.3145 J/(mol · K). If p is in atmospheres and V is in liters, use R = 0.08206 L atm/(mol-K) instead. Part A A gas sample enclosed in a rigid metal container at…

An ideal gas is confined to a constant volume container and heated from a pressure of 1 atm at room temperature to a pressure of 5 atm. What is the final temperature.  Thank you for the help. I got 297K but I do not think that is it.

Can you please solve the below problem, showing step by step: A balloon contains mostly helium and a little nitrogen.  The pressure of the helium is 425 mm Hg.  What is the partial pressure of the nitrogen if the total pressure of the balloon is 67.98 kPa?

This is a calculation only. Energy2d isn’t able to do phase changes as far as I’ve learned. There was a different simulation for this but it is not currently free.   You combine 50g of ice at -10oC with 150g of liquid water at 75oC. After a few minutes, you measure the final equilibrium temperature of all of the H2O to be 35.1 oC. Use this information to “experimentally” determine the heat of transformation of water, Lfusion. cwater=4190 J/kgK, cice=2090 J/kgK   Show all of your work and compare to the accepted value Lfusion=3.33x105 J/kg.

A tank of N2 gas has temperature 500 K. Calculate the percentation of N2 molecules that has a speed between 1000 m/s and 2000 m/s. ____% 2 sig. fig. Please solve in Excel numerically the Maxwell-Boltzmann distribution

You are studying a liquid that you have just synthesized in the laboratory, and you would like to get a rough idea of its enthalpy of J -), you measure its normal boiling point and find that it is mol.
