Question #3188c

Answer 1

Using Charles Law, `V_1/T_1 = V_2/T_2`, the answer is 3.05 L.

Explanation:

Charles law is `V_1/T_1 = V_2/T_2`
first convert the temperatures to kelvin by adding 273.
22 + 273 = 295
3.5 + 273 = 276.5

substitute:
295 for `T_1`
3.25 for `V_1`
276.5 for `T_2`

`3.25/295 = V_2/276.5`

solve for `V_2` (by multiplying both sides by 276.5) and the answer is 3.05 L.

Note: you can only use Charles law when the other factors, pressure and moles, are constant. If everything is changing, use the combined gas law, `(P_1V_1)/T_1 = (P_2V_2)/T_2`
