The first law of thermodynamic is expressed as:
1 $\mathrm{q}-\mathrm{W}=\Delta \mathrm{E}$
2 $\Delta \mathrm{E}=\mathrm{q}-\mathrm{W}$
3 $q=\Delta \mathrm{E}-\mathrm{W}$
4 $\mathrm{W}=\mathrm{q}+\Delta \mathrm{E}$
5 none of the these
Explanation:
The first law of thermodynamics can be expressed as - $\Delta \mathrm{E}=\mathrm{q}+\mathrm{W}$ $\mathrm{q}=\Delta \mathrm{E}-\mathrm{W}$

Deviation from the ideal gas behaviour of a gas can be expressed as :
1 $\mathrm{Z}=\frac{\mathrm{P}}{\mathrm{VRT}}$
2 $\mathrm{Z}=\frac{\mathrm{PV}}{\mathrm{nRT}}$
3 $\mathrm{Z}=\frac{\mathrm{nRT}}{\mathrm{PV}}$
4 $\mathrm{Z}=\frac{\mathrm{VR}}{\mathrm{PT}}$
Explanation:
According to ideal gas equation, $\mathrm{PV}=\mathrm{nRT}$ $\mathrm{n}=$ number of mole of gas Therefore compressibility factor $\mathrm{Z}=\frac{\mathrm{PV}}{\mathrm{nRT}}$ For an ideal gas $Z=1$ and for real gas, $Z$ may be either greater than one or less than one.

"The mass and energy both are conserved in an isolated system" is the statement of
1 second law of thermodynamics
2 third law of thermodynamics
3 modified first law of thermodynamics
4 first law of thermodynamics
Explanation:
Modified first law of thermodynamicsAccording to this law, if a certain amount of one kind of energy is produced, an equal amount of some other kind of energy is consumed so that the total energy in the universe remains constant. The modified first law of thermodynamics states that "In an isolated system, both mass and energy are conserved".
