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

To determine which expressions are correct variations of the Combined Gas Law, we need to start with the standard form of the Combined Gas Law: Let's analyze each given expression:1. **Expression 1:** Rearranging the Combined Gas Law to solve for , we have: This matches the given expression, so Expression 1 is correct.2. **Expression 2:** Rearranging the Combined Gas Law to solve for , we have: This matches the given expression, so Expression 2 is also correct.Therefore, both expressions are correct variations of the Combined Gas Law. The answer is:**both expressions are correct**
