A gas with an initial volume of 6.5 dm $^2$ is heated and allowed to expand to 19.5m $^2$ at constant pressure. What is the ratio of the initial absolute temperature to the final absolute temperature?

A. 2:5

B. 4:5

C. 3:8

D. 1:3

Correct Answer:
1:3

Explanation

V $_1$ = 6.5 dm $^3$ , V $_2$ = 19.5dm $^3$
$\frac {V_1}{T_2}$ = $\frac {V_2}{T_2}$ , $\frac {T_1} {T_2}$ = $\frac {V_1}{V_2}$
= $\frac {6.5dm^3}{19.5dm^3}$
=1:3

V $_1$ = 6.5 dm $^3$ , V $_2$ = 19.5dm $^3$

$\frac {V_1}{T_2}$ = $\frac {V_2}{T_2}$ , $\frac {T_1} {T_2}$ = $\frac {V_1}{V_2}$

= $\frac {6.5dm^3}{19.5dm^3}$

=1:3
