The first law of thermodynamics is a statement of:

1. Conservation of mass

2. Conservation of linear momentum

3. Conservation of energy

4. Conservation of angular momentum

A mixture of two moles of carbon monoxide and one mole of oxygen, in a closed vessel is ignited to convert the carbon monoxide to carbon dioxide. If ΔH is the enthalpy change and ΔE is the change in internal energy, then:
1. ΔH > ΔE
2. ΔH < ΔE
3. ΔH = ΔE
4. The relationship depends on the capacity of the vessel

The relation between ΔE and ΔH is [MP PET 1992; MP PMT 1996; MP PET/PMT 1998]

1. $\mathrm{\Delta H}=\mathrm{\Delta E}-\mathrm{P}\hspace{0.17em}\mathrm{\Delta V}$

2. $\mathrm{\Delta H}=\mathrm{\Delta E}+\mathrm{P}\hspace{0.17em}\mathrm{\Delta V}$

3. $\mathrm{\Delta E}=\mathrm{\Delta V}+\mathrm{\Delta H}$

4. $\mathrm{\Delta E}=\mathrm{\Delta H}+\mathrm{P}\hspace{0.17em}\mathrm{\Delta V}$

At constant T and P, which one of the following statements is correct for the reaction, $\mathrm{CO}\left(g\right)+\frac{1}{2}{\mathrm{O}}_2\left(g\right)\to {\mathrm{CO}}_2\left(g\right)$

(1) ΔH is independent of the physical state of the reactants of that compound

(2) ΔH > ΔE

(3) ΔH < ΔE

(4) ΔH = ΔE

For the reaction of one mole of zinc dust with one mole of sulphuric acid in a bomb calorimeter, ΔU and w correspond to

(1) $\mathrm{\Delta }U<0,\hspace{0.17em}w=0$

(2) $\Delta \text{U}=0,w<0$

(3) $\Delta \text{U}>0,w=0$

(4) $\Delta \text{U}<0,w>0$
