The cylinder is completely insulated from its surroundings. As a result, no heat is exchanged between the system (cylinder) and its surroundings. Thus the process is ‘Adiabatic’.

Let the initial and final pressure inside the cylinder be $P_1$ & $P_2$ and volume be $V_1$ & $V_2$ .

Ratio of specific heat, $\gamma$ = 1.4

For an adiabatic process, we know $P_1{V}_1^{\gamma }$ = $P_2{V}_2^{\gamma }$

It is given $V_2=$ $\frac{V_1}{2}$

Hence $P_1{V}_1^{\gamma }$ = $P_2{\frac{V_1}{2}}^{\gamma }$ or $\frac{P_2}{P_1}$ = ( $V_1^{\gamma })/$ ( ${\frac{V_1}{2}}^{\gamma })$ = $2^{\gamma }$ = $2^{1.4}$ = 2.639

Hence the pressure increases by a factor of 2.639

Mass of Nitrogen, m = 2.0 × ${10}^{-2}$ kg = 20 g

Rise in temperature,  $?T$ = 45 °C

Molecular mass of $N_2$ . M = 28

Universal gas constant, R = 8.3 J mol–1 K–1

Number of moles, n = $\frac{m}{M}$ = $\frac{20}{28}$ = 0.714

Molar specific heat at constant pressure for nitrogen,  $C_p$ = $\frac{7}{2}$ R = 29.05 J/mol/K

The total amount of heat to be supplied is given by the relation

$?$ Q = n $C_p?T$ = 0.714 $\times 29.05\times 45$ = 933.38 J

Students often get confused while selecting a college during the admission season. The best way to solve this problem is compare colleges based on certain parameters. Aptech Computer Education Mumbai can be compared with other institutes for its certificate courses based on fees, student reviews, placement support, etc. 

Initial temperature,  $T_1$ = 27 °C

Final temperature,  $T_2$ = 77 °C

Rise in temperature,  $?T=T_2-T_1=50?$

Heat of combustion = 4.0 × ${10}^4$ J/g

Specific heat of water, c = 4.21 J/g/ $?$

Mass of flowing water, m = 3 lit/min = 3000 g/min

Total heat used,  $?Q=mc?T$ = 3000 $\times 4.21\times 50$ = 6.315 $\times {10}^5$ J/min

Rate of consumption = $\frac{6.315\mathrm{}\times {10}^5}{4.0\mathrm{}\times \mathrm{}{10}^4}$ g/min = 15.79 g/min
