The change in internal energy for the combustion of 1.0 of octane at a pressure of 1.0 is 5084.1 If the change in enthalpy is 5074.3 how much work is done during the combustion?
The work done during the combustion process can be calculated using the equation: ΔH = ΔU + PΔV. Since the process is done at a constant pressure, the work done is equal to the change in enthalpy minus the change in internal energy: W = ΔH - ΔU = 5074.3 - 5084.1 = -9.8 J. Therefore, 9.8 J of work is done during the combustion.
How is pressure volume equal to a joule?
In the context of thermodynamics, work done on a gas can be calculated using the formula W = PΔV, where P is pressure and ΔV is the change in volume. Since work done is measured in joules, pressure multiplied by volume change gives the work done in joules.
When an ideal gas expands in vacuum work done is?
When an ideal gas expands in a vacuum, no work is done because there is no external pressure against which the gas can expand. In this case, the expansion is considered to be isentropic, meaning that there is no change in entropy of the system.
Do eggs float when they are done boiling?
Yes, eggs that are done boiling may float because the air pocket inside the egg expands as it cooks, causing it to become less dense and float in water.
The work done to move one electron in a light bulb is very small?
The work done to move one electron in a light bulb is small because electrons are lightweight particles with a small charge. The work done is a result of the electric field in the circuit, which provides the energy for the movement of electrons to create light.
