Let M represent a certain mass of coal which we assume will deliver 100 joules of heat when burned – whether in a house, delivered to the radiators or in a power plant, delivered at 1000°C. Assume the plant is ideal (no waste in turbines or generators) discharging its heat at 30°C to a river. How much heat will M, burned at the plant to generate electricity, provide for the house when the electricity is: (a) delivered to residential resistance-heating radiators? (b) delivered to a residential heat pump (again assumed ideal) boosting heat from a reservoir at 0°C into a hot-air system at 30°C?

The vapour pressure of water can be given by: , being p the vapour pressure in mmHg and T in K. Assuming the normal boiling temperature of water is 100 ºC, calculate the value of A. Vacuum has been created in a 10 L vessel, and 10 g water have been introduced. We will assume that vapour is an ideal gas, and the density of liquid water is 1 g/cm3 at any temperature. Calculate the mass of water in liquid phase at 50 ºC: a) Assuming the volume of the liquid is very small and therefore we can ignore it; b) considering the volume occupied by the liquid water. Results:. A = 8.564; a) 9.105 g ; b) almost the same!

Draw what the heating curve would look like for a sample of liquid water at 35degC heated to steam at 120degC. Label your starting temperature, ending temperature, boiling point and the states of matter along the line of the curve. Use the graph to calculate the total energy required to raise the temperature of 225g of water from 35degC to 120degC. (Hint: Only 3 calculations are required.) deltaHvap = +40.7 kJ/mol. c(water) = 4.18 J/g deg. c(steam) = 2.02 J/g degC *

I need help solving number 11. In question 1, they say U=(3/2)PV I found work on the gas as -3/2PV, so therefore Q should be 6/2PV but the answer key says 6PV.
An ideal monatomic gas is contained in a cylinder with a movable piston so that the gas can do work on the outside world, and heat can be added or removed as necessary. (Figure 1) shows various paths that the gas might take in expanding from an initial state whose pressure, volume, and temperature are po, Vo, and To respectively. The gas expands to a state with final volume 4V. For some answers it will be convenient to generalize your results by using the variable R₂ = Vfinal/Vinitial, which is the ratio of final to initial volumes (equal to 4 for the expansions shown in the figure.) The figure shows several possible paths of the system in the pV plane. Although there are an infinite number of paths possible, several of those shown are special because one of their state variables remains constant during the expansion. These have the following names: Adiabatic: No heat is added or removed during the expansion. • Isobaric: The pressure remains constant during the expansion. ● •…
