Question

A piston-cylinder device contains a mixture of 1.0 kg of H2, and 1.6 kg of N2 at 100 kPa and 300K. Heat is now transferred to the mixture at constant pressure until the volume is doubled. Assuming constant specific heats at the average temperature. Determine the heat transfer to the system. Refer to Table A-2(b) for the constant pressure specific heats values.

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.

Use the data: P1 = 1 atm, P2 = 4 atm, V1 = 5 L, V2 = 20 L. (Path AB is an "isothermal" which means the temperature T is constant on this path). a) 0.012 J b) 1220 J c) 0.0278 J d) 2809 J
A container is filled with an ideal diatomic gas to a pressure and volume of P1 and V1, respectively. The gas is then warmed in a two-step process that increases the pressure by a factor of five and the volume by a factor of four. Determine the amount of energy transferred to the gas by heat if the first step is carried out at constant volume and the second step at constant pressure. (Use any variable or symbol stated above as necessary.)

Problem 4: Consider a cylinder with a movable piston containing n moles of an ideal gas. The entire apparatus is immersed in a constant temperature bath of temperature T Kelvin. The piston pushes slowly outward on an external body which matches the force momentarily at each instant so that the gas expands quasi-statically from a volume V1 to V2 at constant temperature T. The isothermal process is shown in the figure above, where the pressure p is related to the volume V by the ideal gas law as follows: pV = nRT, where R is the gas constant. Part (b) For n = 3 moles, T = 350 K, and V2 = 2.5V1, determine the work done by the gas on the external body. The gas constant is R = 8.314 J K-1 mol-1.
Ice at -12.1 °C and steam at 121 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 44.1 °C is present. Ignoring the container and the equilibrium vapor pressure of the liquid at 44.1 °C, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020 J/(kg C°). af Number i Initial state Units Steam - Ice Equilibrium Water

Part A: If you supply 2950 J of heat to 6.00 moles of an ideal diatomic gas initially at 23.0 ∘C in a perfectly rigid container, what will be the final temperature of the gas? Express in degrees Celsius. Part B: Suppose the gas in the container were an ideal monatomic gas instead. How much heat would you need to add to produce the same temperature change? Part C: Which pV diagram expresses these processes?
