Compute the work done by a gas on the surrounds when it expands against a constant external pressure of 2.00 atm from 5.00 L to 10.00 L at 30C. If 2.00 atm is the gas pressure at 10.00 L, 30C, compute the number of mole of gas. Compute the work that must be done by the surrounds on the gas to return the gas to its initial state using one irreversible compression.
The gas inside a cylinder expands against a constant external pressure of 0.953 atm from a volume of 4.51 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.962 L of liquid toluene (C7H8). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism. Take the density of liquid C7H8 to be 0.867 g cm-3 and its specific heat to be 1.69...
The gas inside a cylinder expands against a constant external pressure of 0.906 atm from a volume of 3.61 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.926 L of liquid octane (C8H18). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism. Take the density of liquid C8H18 to be 0.703 g cm-3 and its specific heat to be 2.22...
How much work is done, in joules, when a piston expands from 11.4 L to 13.6 L against a pressure of 3.0 atm?
An ideal gas expands from 26.0 L to 80.0 L at a constant pressure of 1.00 atm. Then, the gas is cooled at a constant volume of 80.0L back to its original temperature. It then contracts back to its original volume without changing temperature. Find the total heat flow, in joules, for the entire process. total heat flow:
