The pressure in a container has decreased by 10 times, while the volume increased by 5 times from the original volume. the temperature now reads -123.15 °c. what was the starting temperature when i left (in °c)?

The starting temperature when I left in °C is 26.70

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas = p

= final pressure of gas =

= initial volume of gas = v

= final volume of gas =

= initial temperature of gas = ?

= final temperature of gas =

Now put all the given values in the above equation, we get:

answer: (431,2)
