Which of these equations are correct? Select all that apply
nikitadnepr [17]

Answer:

The answer to your question is below

Explanation:

There are 4 laws of gases

- Charles

  \frac{V1}{T1} = \frac{V2}{T2}

- Gay Lussac

 \frac{P1}{T1} = \frac{P2}{T2}

- Boyle - Mariotte

 P1V1 = P2V2

- General law of gases

  \frac{P1V1}{T1} = \frac{P2V2}{T2}

Let's use these formulas to answer the question

p2 = V2/P1                  This is not a law of gases

p1= V1/k                        This formula is similar to Boyle mariotte equation

                                     but is not.

V2 = k/P2                      This equation is correct is Boyle Mariotte formula

V2 = P1V1/ P2               This equation is also correct is Boyle Mariotte formula

V1 = P1/P2 (V2)            This equation is incorrect

P2 = (P1) V1/V2             This equation is correct is Boyle mariotte formula

An Isolated system could be best described as a _______________.
grandymaker [24]
Hello Mate!

Well, there are many definitions and descriptions of isolated systems, and here are some of them:

1. It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.

2. It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.

I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)
