Answer : The correct option is, (c)
Explanation :
First we have to calculate the energy or heat.
Formula used :
where,
E = energy (in joules)
V = voltage (in volt)
I = current (in ampere)
t = time (in seconds)
Now put all the given values in the above formula, we get:
Now we have to calculate the heat capacity of the calorimeter.
Formula used :
where,
C = heat capacity of the calorimeter
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get:
Therefore, the heat capacity of the calorimeter is,
