Energy Value

To determine the energy value in food samples:

i. ground nut

ii. cashew nut
Problem Statement: What are the energy values of different food samples?

Hypothesis: Cashew nut has a higher energy value than ground nut.//vice versa

Variables:

Manipulated: Types of nuts/type of food samples

Responding: Energy value

Fixed: mass of water

Apparatus & Material:

Ground nut, cashew nut, pin, plasticine, cotton wool, thermometer, boiling tube, bunsen burner, electronic balance, distilled water, retort stand, wind shield

Procedure:

List down the procedure. Make sure you include sentences of:

1. How to set up the apparatus. **At least 3 sentences.

2. How to manipulate variables

3. How to get a responding variable

4. How to get fixed variable.

5, Safety measures such as:

-use wind shield to avoid disturbances of wind which will affect the exp result.

**List only one should be sufficient.

This is called ' A simple calorimeter'

Setting up of apparatus

Result:

Produce a Table with manipulated variable and responding variable in a row and column respectively.

Do not forget the unit!!!

Do not forget the formula to calculate the energy value (J/g) of food.

*State the formula please ...
