is that correct?

When does the bottle become dangerously hot?​

Let’s say we put a steel cylinder in the sun that is approved for 232 bar operating pressure (and tested at over 300 bar).

If it has 200 bar at 20 degrees room temperature, at what temperature does it reach the 232 bar?

Solution​

We remember: p1/T1=p2/T2

Temperature: in Kelvin, 20 degrees Celsius – 293 Kelvin

In short, this is converted
p2xT1/p1=T2

232barx293K/200bar=339.8K – 66.8 degrees Celsius

Yep. One of the instructors in their videos spends his days as a physicist working at an observatory on the island.
