First Law of Thermodynamics

If $\mathrm{\Delta H}$ is the change in enthalpy and $\mathrm{\Delta E},$ the change in internal energy accompanying a gaseous reaction, then

Internal energy and pressure of a gas per unit volume are related as:

Explain where the First Law of Thermodynamics failed.

Which of the following is not explained by First Law of Thermodynamics?

First Law of Thermodynamics failed to explain the direction of the convertibility of one form of energy into another.

Amount of heat energy transferred from one system to another was explained by the First Law of Thermodynamics.

What are the limitations of First Law of Thermodynamics?

Define Joule-Thomson Coefficient.

The Joule Thomson coefficient for an ideal gas is equal to _____(positive/zero/negative).

The Joule Thomson coefficient for an ideal gas is positive.

The Joule–Thomson coefficient $\mathrm{\mu }$ is defined as the ratio of the volume change to the pressure drop, and is expressed in terms of the thermal expansion coefficient and the heat capacity.

The Joule–Thomson coefficient $\mathrm{\mu }$ is defined as the ratio of the temperature change to the _____ (pressure/volume) change, and is expressed in terms of the thermal expansion coefficient and the heat capacity.

Using Joule-Thomson Effect describe what happens to the temperature of a gas when throttled through an orifice.

During Joule-Thomson effect, the volume of gas in decreased when throttled through an orifice.

During Joule-Thomson effect, the _____ of gas in decreased when throttled through an orifice.
