Last January 13, 2010 we discussed Calorimetry in our chem class.

I. Calorimetry
- To know the amount of energy released, three things need to be known:

1. Temperature Change (Delta T)
2. Amount of Water (kg)
3. Specific Heat Capacity ---> 4.10 kJ/ kg degrees Celcius (for water)

Here is the equation that we can use for solving Calorimetry problems.




Now here is an example:

1. Calculate the amount of heat recquired to warm 250.0g of water from 10 degrees to 15 degrees celcius.

II. Molar Enthalpy

- Change in heat for each mole reacted

When a candle (C25H52) is burned, heat is released according to the reaction


If 5.0g of wax is burnt, how much heat is released?

Hi, Did you know that the test of all knowledge is experiment. :)
