I think that the sun is the center of the universe, not a human being. Everything revolves around the sun, not someone. U know when to sleep, when the time is, and when to wake up based on the sun. All the planets revolve around it. This is why I think the sun is the center of the universe, not a human being.

Which equation is derived from the combined gas law? StartFraction V subscript 1 over T subscript 1 EndFraction equals StartFrac
ioda

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}
