Why do the planets stay in their orbit around the sun?

The Sun's gravity constantly pulls on the planets, preventing them from leaving their orbit and the solar system. The forward motion of the planets prevents the Sun's gravity from pulling planets straight into it.

Explanation:

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
