schepotkina [342]

Answer: 150m

Explanation:

The following can be depicted from the question:

Dimensions of outer walls = 9.7m × 14.7m.

Thickness of the wall = 0.30 m

Therefore, the plinth area of the building will be:

= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)

= 10 × 15

= 150m

A 2-m^3 rigid tank contains nitrogen gas at 500kPa and 300K. Now the gas is compressed isothermally to a volume of 0.1 m. The wo

stira [4]

Answer:

(d) 2996 kJ

Explanation:

We have given initial volume $v_1=2m^3$

initial pressure $p_1=500\ kPa$

initial temperature $T_1=300\ K$

we know that during isothermal process the work done is given by

$W=p_1v_1ln\frac{v_2}{v_1}$

where $v_2= final\ volume =0.1m^3\ given$

putting all these value in formula of work done

$W=500\times 2\times ln\frac{0.1}{2}$

=-2995.8 kJ here negative sign indicates that work is dine on the gas

so wok done =2995.8 kJ
