What is the relationship between temperature and enthalpy change for an ideal gas?
The relationship between temperature and enthalpy change for an ideal gas is described by the equation H nCpT, where H is the enthalpy change, n is the number of moles of the gas, Cp is the molar heat capacity at constant pressure, and T is the change in temperature. This equation shows that the enthalpy change is directly proportional to the temperature change for an ideal gas.
What is the enthalpy equation for an ideal gas?
The enthalpy equation for an ideal gas is H U PV, where H is enthalpy, U is internal energy, P is pressure, and V is volume.
What is the relationship between enthalpy and temperature change during an adiabatic expansion process?
During an adiabatic expansion process, there is no heat exchange with the surroundings. As a result, the change in enthalpy is directly related to the change in temperature. When a gas expands adiabatically, its temperature decreases, leading to a decrease in enthalpy.
When does enthalpy become zero?
Enthalpy can be zero for a pure substance at its standard state, where it is defined as the enthalpy of formation. This typically occurs at a reference temperature and pressure specified for the substance.
Why is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?
Enthalpy is a state function, and to a first approximation does not depend on temperature. So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.
What factor does the enthalpy of an ideal gas depend on exclusively?
The enthalpy of an ideal gas depends exclusively on its temperature.

What is the relationship between internal energy and the behavior of an ideal gas?
The internal energy of an ideal gas is directly related to its temperature. As the temperature of an ideal gas increases, its internal energy also increases. This relationship is described by the equation for the internal energy of an ideal gas, which is proportional to the temperature of the gas.
What happens to the volume of a gas when the temperature doubles?
In a perfectly flexible and expandable container (pressure is constant) the volume of an ideal gas will double as the absolute temperature doubles. For a non-ideal gas and non-perfect container, your results will vary but will always be somewhat less than double.

What is the volume of an ideal gas at absolute zero temperature?
At absolute zero temperature, the volume of an ideal gas would theoretically be zero.
What is the relationship between pressure and temperature in an ideal gas?
In an ideal gas, the relationship between pressure and temperature is described by the ideal gas law, which states that pressure is directly proportional to temperature when volume and amount of gas are constant. This means that as temperature increases, so does pressure, and vice versa.
Why joule Thomson coefficient is zero for ideal gases?
The Joule-Thomson coefficient is zero for ideal gases because ideal gases do not exhibit any intermolecular forces that would cause them to deviate from ideal behavior. As a result, there is no energy exchange during expansion or compression, leading to a zero Joule-Thomson coefficient for ideal gases.
When does enthalpy become zero?
Enthalpy can be zero for a pure substance at its standard state, where it is defined as the enthalpy of formation. This typically occurs at a reference temperature and pressure specified for the substance.
What law relates pressure and temperature at a constant volume as temperature increases pressure increases?
The ideal gas law, also known as the equation of state for an ideal gas, relates the pressure, volume, and temperature of an ideal gas if the volume is kept constant. This law states that when the temperature of an ideal gas increases at constant volume, the pressure of the gas will also increase.
