Question

Which equation is derived from the combined gas law? StartFraction V subscript 1 over T subscript 1 EndFraction equals StartFraction V subscript 2 over T subscript 2 EndFraction. StartFraction V subscript 1 over T subscript 2 EndFraction equals StartFraction V subscript 2 over T subscript 1 EndFraction. V subscript 1 T subscript 1 equals P subscript 2 T subscript 2. P subscript 1 V subscript 1 T subscript 1 equals P subscript 2 V subscript 2 T subscript 2.

Answer 1

Answer:

$\frac{V_!}{T_1} =\frac{V_2}{T_2}$

Explanation:

hello,

the combined gas law equation is given as;

$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$

This combined gas law is gotten from the combination of Charles' law, Boyle's law and the Pressure law.

At constant pressure(this means the pressure is unchanged or fixed and this means the pressure is eliminated), we have:

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

At constant volume(we eliminate the volume since it is fixed or unchanged), we have;

$\frac{P_1}{T_1} = \frac{P_2}{T_2}$

At constant temperature (we also eliminate temperature), we have

$P_1V_1 = P_2V_2$.

thus from the options provided in the question the right answer will be

$\frac{V_!}{T_!} = \frac{V_2}{T_2}$
