Question

At standard temperature a gas has a volume of 275 mL. If the temperature is increased to 130°C, but the pressure is held constant, what is the new volume?

Answer 1

Well, old Charles' Law holds that

V

∝

T

at constant pressure......for a given quantity of gas.....

Explanation:

So if

V

∝

T

, then

V

=

k

T

; if we solve for

k

under different conditions of volume and temperature.....

V

1

T

1

=

V

2

T

2

, temperature is measured in

degrees Kelvin

.

And

V

2

=

V
