Question

Charles's Law states that at constant pressure, the volume of a fixed amount of gas varies directly with its temperature measured in degrees Kelvin. A gas has a volume of 250 mL at 300 K.

what is an equation for the relationship between volume and temperature?

Answer 1

Volume=constant*temperatureinK
250ml=constant*300k
constant = 250/300 mL/K

equation then is
Volume=(250/300 mL/K)*tempinK

Answer 2

V = constant * T
250 mL = constant * 300 K
constant = 250 mL/300 K = .833... mL/K
so
V = .833 T
