Working with a lab partner, a gas sample is prepared with a pressure of 1.25 bar at T = 350 K. You leave the room for a few minutes, duringwhich time your lab partner alters the sample so that it has a pressure of 0.75 bar and T = 210 K, but you don't know how this was done.You carefully restore the system to its initial conditions and determine that the enthalpy change for the process you used was AH = 427 J.What enthalpy change occurred for the process your lab partner performed while you were gone?OOJ427 JO-427 JO cannot be determined

If mercury overflows, it’ll trigger an alarm in the lab. The teacher wants to keep the lab at exactly 16.37 ◦C. While the mercury alarm is in place. How long would a person of average body size (surface area of about 1.8 m2 and normal body temperature of 37◦C) have to spend in the lab which holds 2700 moles of air to trigger the mercury alarm? Side note: The maximum temperature the lab can heat the system to (to the thousandth of a degree Celsius) before the mercury overflows is 16.37◦C. Please show all work with equations that are used.
A process that takes place under constant temperature and pressure is spontaneous if AG > 0. True False
Two evacuated bulbs are connected by a tube of negligible volume. The volume of one of the bulbs is twice that of the other. The larger volume bulb is placed in a 200K Isother constant-temperature bath and the other in a 300K bath, and then 1.00mol of an ideal me gas is injected into the system. Find the final number of moles of gas in each bulb.
A student decides to conduct an experiment by using two different flasks and two different gas samples. In flask 1, there exists Neon (Ne) gas, whereas the second flask is filled with nitrogen (N2) gas. If both flasks are kept at 270 K, answer the following questions. (Note: Molar mass of N2 = 28.014 g mol1,molar mass of Neon = 20.1797 g mol, R= 8.31 J. mol1.K1, k=1.38 x 1023 J.K-1, Avogadro's number = 6.02 x 1023 mol1.) a) Find the average kinetic energy of one Neon molecule. b) Calculate the average kinetic energy (translational+rotational) of one nitrogen molecule by including rotational motion in your calculations. c) Find the root-mean-square speed of one neon molecule.

Suppose you put 2.00 kg of pure liquid water, initially at 0.00°C, in a room. The temperature of the room is T room= −10.0 ° C . Assume the system of the room plus the water is thermally isolated, i.e. a closed system. Lf , water=3.34×10^5 J/kg The process you will be analyzing is the following: The water transfers heat into the room, such that the water freezes to form a 2.00 kg block of pure ice, still at 0.00°C. The room is large enough that its temperature remains constant at -10.0°C during this process. a) Find the change in the entropy of the water/ice during this process. b) Find the change in the entropy of the room during this process. c) Comment on the likelihood that this freezing process will occur, using the ideas of the Second Law of Thermodynamics and microstates in your explanation
