Which of these expressions are correct variations of the Combined Gas Law? both of the above P_(1)V_(1)T_(2)=P_(2)V_(2)T_(1) P_(2)=P_(1)((T_(2))/(T_(1)))((V_(1))/(V_(2)))

The Combined Gas Law is expressed as: To determine if the given expressions are correct variations of the Combined Gas Law, let's analyze each one.1. Starting from the Combined Gas Law: Multiplying both sides by to eliminate the denominators: This matches the first expression, so it is correct.2. \( P_{2}=P_{1}\left(\frac {T_{2}}{T_{1}}\right)\left(\frac {V_{1}}{V_{2}}\right) \)Starting again from the Combined Gas Law: Rearranging to solve for : This matches the second expression, so it is also correct.Therefore, both expressions are correct variations of the Combined Gas Law. The correct answer is:**both of the above**
