4) I need your help for question attached. note: required data is also attached.
So each four dot shows four different states for an ideal gas. P is the pressure and the other one is the density of the gas. Is temperature of state 1 less or greater than the state 2? Can you please explain why?

Review 8-64 (algorithmic) Question Help ▼ When boiling water, a hot plate takes an average of 8 minutes [min] and 35 seconds [s] to boil 110 milliliters [mL] of water. Assume the temperature in the lab is 71 degrees Fahrenheit ["F]. The hot plate is rated to provide 385 watts [W]. If we wish to boil 110 milliliters [mL] of acetone using this same hot plate, how long do we expect the process to take? Acetone has a boiling point of 56 degrees Celsius [c].

26) A system of two moles of an ideal gas increases its internal energy by 1000 J as it increases in temperature from 300 K to 340 K. There are no changes in bond energy. Which of the following statements is true? A: This gas is monatomic. B: Not enough information given; you need to know how much work was done on the gas. C: This gas is diatomic, with its vibrational modes unfrozen. D: Not enough information given; you need to know how much heat was transferred to the gas. E: This gas is diatomic, with its vibrational modes frozen out.
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.
