An isolated gas (nitrogen, N2), at initial temperature of 22.7 degrees Celsius, is expanded from as initial volume of 0.750L to 1.450L at constant pressure, P=132kPa. During this process the gas absorbs 318.5J of heat. i. Calculate the work output by the system during this expansion ii. Estimate the specific heat capacity of the gas for this process. Express your answer in J/kg*K.

In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius
In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius. The walls have fiberglass insulation, which dominates the heat conduction properties of the wall So we can consider the wall to have a thermal conductivity of k(wall) = 0.048 W/m/K . We will take the thickness of the walls and ceiling to be L(wall) = 12...

Given that the initial rate constant is 0.0180s−1 at an initial temperature of 30 ∘C , what would the rate constant be at a temperature of 180. ∘C for the same reaction described in Part A? Express your answer with the appropriate units. (I solved this and got 2.01, which is wrong, but I'm not exactly sure why). (Reaction A was: The activation energy of a certain reaction is 44.3 kJ/mol . At 30 ∘C , the rate constant is...
