Calorimeter

How many calories does it take to raise the temperature of one gram of water by one degree?

We will determine calorie content of varying foods using a homemade calorimeter.

Procedure:

1.       Measure 25 g of each substance.

2.       Measure out 100 g of water.

3.       Grab all materials.

4.       Make chart.

5.       Light food aflame.
6. Record Data.

Ocean Creatures	25	19	22	3
Chocolate Cremes	24	22	22		-1
Swirly Gummy Bears	25	22	22
Potato Chips	24	22	32	10	-1
Sweet Potato Chips	13	35	53	18	-12
Tortilla Chips	14	33	64	31	-11
Sunflower Seeds	28	27	35	8	+3
Pumpkin Seeds	24	32	34	2	-1
Roundy Crackers	27	34	34		+2
Pita Chips	21	31	55	24	-4
Peaches	25	33

Observations:

Ocean Creatures	Flame died out a lot
Chocolate Cremes	Refused to light aflame
Swirly Gummy Bears	Inflammable
Potato Chips	Flickered in and out of flame
Sweet Potato Chips	Crazy good burn
Tortilla Chips	Flame quickly
Sunflower Seeds	Died out quickly and consistently
Pumpkin Seeds	Inflammable
Roundy Crackers	Char better than they burn
Pita Chips	Quick and awesome burn
Peaches	Inflammable
Mangos	Inflammable
Orange Sugar Wafers	Edges burnt very well
Nilla Wafers	Inflammable
Marshmallows	Crispy and yummy looking

Calculations for those that could be done:

Ocean Creatures	(100g)(3C)=300g/C
Potato Chips	(100g)(10C)=1000g/C
Sweet Potato Chips	(100g)(18C)=1800g/C
Tortilla Chips	(100g)(31C)=3100g/C
Sunflower Seeds	(100g)(8C)=800g/C
Pumpkin Seeds	(100g)(2C)=200g/C
Pita Chips	(100g)(24C)=2400g/C
Marshmallows	(100g)(10C)=1000g/C
