A container with a volume of 12 L contains a gas with a temperature of 210 K. If the temperature of the gas changes to 420 K without any change in pressure, what must the container's new volume be?

Just apply Charle's law for constant pressure and mas of an ideal gas,

So,we have,

V/T=k where, k is a constant

So,we putting the initial values of V and T we get,

k=12/210

Now,if new volume is V' due to temperature 420K

Then,we get,

(V')/420=k=12/210

So,V'=(12/210)×420=24L

The new volume is 24 liters or 24 \ "L".

Explanation:

Since there is no change in temperature and the number of moles, we use Charles's law, which states that

VpropT

or

V_1/T_1=V_2/T_2

Solving for V_2, we get:

V_2=T_2*V_1/T_1

Plugging in the given values, we find that

V_2=420color(red)cancelcolor(black)"K"*(12 \ "L")/(210color(red)cancelcolor(black)"K")

=24 \ "L"
