Sedimentary rocks are turned into metamorphic rocks by heat and pressure
Answer:
its more than likely substance #1
Explanation:
The given data is as follows.
Moles of propylene = 100 moles,
= 100 J/mol K
= 300 K,
= 800 K
= 2
,
= 0.02 ![m^{3}](https://tex.z-dn.net/?f=m%5E%7B3%7D)
Therefore, the assumptions will be as follows.
- The given system is very well insulated.
- The work is done on the system because the given process is a compression process.
- Assume that there is no friction so, work done on the system is equal to the heat energy liberated.
= W
Putting the given values into the above formula as follows.
= W
W =
=
J
= 5 MJ
Hence, this shows that a minimum of 5 MJ work needs to be done.
Since, work is very less. Hence, it will not compress the given system to 800 K and 0.02
.

its hard to explain simply because i dont have a mastery over the subject yet myself, but this article should help explain it
if you have any questions, leave them in the comments and i will try to answer them, if this helped, pls give brainliest
