Explanation / Answer

Answer:

Part A:

From Ideal gas equation PV=nRT

Where P=pressure, V=volume, n=amount of gas, R=gas constant and T=absolute temperature.

At constant pressure and amount of gas, Volume of gas is directly proportional to temperature.

Therefore V1/V2=T1/T2

Given V1=1.52x10^3 L and T1=24°C=24+273K=297 K.

V=? At T2=78°C=78+273 K=351 K

V2=V1T2/T1

V2=(1.52 x10^3 L x 351 K)/297 K

V2=1796.36 L=1.796x10^3 L.

Part B: Here also same formula V1/T1=V2/T2 can use.

Given V1=1.52 x10^3 L and T1=24°C=297 K,

V2=3.04x10^3 L, T2=?

T2=V2T1/V1=(3.04x10^3 L x 297K)/(1.52x10^3L)

T2=594 K=321°C (Since 0°C=273 K, 594K=594-273 =321°C)
