Thank you very much. I needed help with one more.
A bomb calorimeter evolves 4.66 kJ of heat. If the heat capacity of the calorimeter is 1.38 kJ/Celsius, what is the temp change of the calorimeter?
I thought it may be 4.66/1.38= 3.38?
try this heat=heat capacity * temperature change. just apply this formula heat evolve will be the heat. heat capacity is that of the calorimeter and temperature change is the unknown. use it
First off, go back and look at your former posts. Bob Pursley pointed out to me that you had 669 kJ in your first answer and that's a good answer. You would not need to express it as 6.69 x 10^5 Joules although that would be correct.
That's what I would do. Again, you need units stuck on the end; in this case it is degrees C or degrees K.
To find the temperature change of the calorimeter, we need to use the equation:
Heat (q) = Heat Capacity (C) * Temperature Change (ΔT)
In this case, we know the heat evolved by the calorimeter is 4.66 kJ and the heat capacity is 1.38 kJ/Celsius.
Rearranging the equation, we have:
Temperature Change (ΔT) = Heat (q) / Heat Capacity (C)
Substituting the given values:
ΔT = 4.66 kJ / 1.38 kJ/Celsius
Now, let's calculate:
ΔT = 3.38 Celsius
So the temperature change of the calorimeter is 3.38 Celsius.
Your calculation of 4.66 / 1.38 = 3.38 is correct!
