1 Point
Charles's law describes the relationship of the volume and temperature of
gas at a constant mass and pressure. According to this law, what would
happen to the volume of the gas if its temperature decreased from 400 K to
300 K?
O
A. The volume would decrease from 400 mL to 300 mL.
B. The volume would be 3/4 of its original value.
C. The volume would increase by 100 mL.
D. The volume would be 4/3 of its original alue.
SUBMIT

Option B. The volume would be 3/4 of its original value.

Explanation:

T1 = 400K

T2 = 300

V1 = V

V2 =?

V1 /T1 = V2 /T2

V/400 = V2 /300

Cross multiply to express in linear form

400 x V2 = 300 x V

Divide both side by 400

V2 = 300V/400

V2 = (3/4)V

Therefore, the new volume will be 3/4 of the original volume.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
