Answer: p2 = 1.06p1
Explanation: pressure increases with temperature increase.
According to Gass law
P1/T1 = P2/T2
T1 = 20°c = 20 +273 = 293k
T2 = 40°c = 40 +373 = 313k
Therefore
P2 = P1T2/T1 = 313P2/293
P2 = 1.06P1

Answer : The correct option is, 
Explanation :
Formula used :
where,
= heat released = 24 KJ
= mass of bomb calorimeter = 1.30 Kg
= specific heat =
= final temperature = ?
= initial temperature =
Now put all the given values in the above formula, we get the final temperature of the calorimeter.

Therefore, the final temperature of the calorimeter is, 
Sodium Chloride because its still a liquid at the 773 temperature mark<span />
