Where’s the rest of the question
Answer: a) 
Explanation:
As we know that,
where,
q = heat released = -600.2 J
= mass of iron rod =100 g
= final temperature =
= initial temperature = ?
= specific heat of iron = 
Now put all the given values in equation, we get
![-600.2J=100\times 0.452J/g^0C\times (25.0-T_{initial})^0C]](https://tex.z-dn.net/?f=-600.2J%3D100%5Ctimes%200.452J%2Fg%5E0C%5Ctimes%20%2825.0-T_%7Binitial%7D%29%5E0C%5D)
Therefore, the initial temperature of iron rod was
Because in a smaller container, there is less room for the gas to exist. the gas much all push together closer to fit in the smaller container. as gas atoms, they have less room to bounce around. in a bigger container, it has more room to more and is less pressurized
