2 answers:
Answer: Option (A) is the correct answer.
Explanation:
It is known that to convert temperature from degree celsius to kelvin we have to add 273 into the given temperature.
Whereas when we have to convert temperature from kelvin to degree celsius then we have to subtract 273.
So, convert 96 K into degree celsius as follows.
=
Thus, we can conclude that 96 K equals .

Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
