A sample of oxygen gas with a volume of 3.0 m3 is at 100 C. The gas is heated so that

vesna_86 [32]

$\qquad\qquad\huge\underline{{\sf Answer}}$

According to Charles law, if pressure remains constant, volume varies directly with temperature. so we can infer that :

$\qquad\sf{\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}$

So, we can use this formula to find out the final temperature of the gas ~

Note : Take temperature in Kelvin ( 100°C = 373 K )

$\qquad \sf \dashrightarrow \: \dfrac{3}{373} = \dfrac{6}{x}$

$\qquad \sf \dashrightarrow \: x = \dfrac{6}{3} \times 373$

$\qquad \sf \dashrightarrow \: x = 2 \times 373$

$\qquad \sf \dashrightarrow \: x =74 6 \: K$

Now, convert it to Celsius ~

i.e 746 - 273 = 473° C

So, the final temperature of the gas will be equal to 473° C
