Question

what will be the volume of a gas when 3 litres of it is cooled down from 15° C to -73°C at constant pressure​

Answer 1

Answer:

x= -14.6 L

Explanation:

V 1= 3L        TEMP 1= 15

V 2= X          TEMP 2= -73

FORMULA IS VOLUME 1 /TEMPERATURE 1 = VOLUME 2 / TEMPERTAURE 2

THEREFORE

3 / 15 = x / -73

SOLVE FOR X BY MAKING X THE SUBJECT OF THE FORMULA

3 / 15 = 0.2

0.2 = X / -73

TAKE -73 TO THE OTHER SIDE BY DOING OPPOSITE OPERATION

WHICH IF * -73

(0.2) * (-73) = x

x= -14.6 L
