Why isothermal process is very slow?

Why isothermal process is very slow?

The isothermal process is slow because the temperature of the system must remain constant. To maintain a constant temperature, the heat transfer process must happen slowly and keep the temperature equal between itself and an outside reservoir.

Which of the following does the internal energy of an ideal gas depend upon?

The internal energy and enthalpy of ideal gases depends only on temperature, not on volume or pressure. We can prove these property of ideal gases using property relations.

What is the change in the internal energy of the gas in the full cycle?

Because the process is cyclic, there is no change in internal energy after each cycle. Therefore the net work done in each cycle equals the heat added to the system.

When ideal gas is compressed isothermally then its pressure increases because?

Since in the given case it is said that we compress the volume; the volume of the gas decreases. We know that as the volume decreases, area also decreases. So, when the area decreases the number of collisions per unit area increases. This causes the increase in pressure.

When an ideal gas in a cylinder is compressed isothermally?

When an ideal gas in a cylinder was compressed isothermally by a piston, the work done on the gas was found to be 1.5×10^4 joules.

What happens when enthalpy is zero?

Temperature is held constant, therefore the change in energy is zero (U=0). So, the heat absorbed by the gas equals the work done by the ideal gas on its surroundings. Enthalpy change is also equal to zero because the change in energy zero and the pressure and volume is constant.

When an ideal gas is compressed adiabatically its temperature?

When an ideal gas is compressed adiabatically, its temperature riese, because heat produced cannot be lost to the surroundings. Each molecules has more KE than before because of collisions of molecules with moving parts of the wall (i.e. Piston compressing the gas).
