You add 30mL of water with a starting temperature of 22* C. After burning the marshmallow your water temperature is about 27* C, how and Calories were in your marshmallow
You know, I really like white marshmellows, I could probably eat a few bags or them.
Mmm, it would all be in the name of science.
Trouble is I like them toasted on an open fire, the drippier the better, I don't mind even if they catch fire and get a bit burnt.
That might stuff up the experiment a bit though. This must be thought through properly :/
Ok so marshmellows are sugar a little salt, and a little other carbohydrate.
That sound really healthy :/

Use energy = mass*specificheat capacity*temperature rise:
Assume density of water = 1000kg/m3, specific heat capacity of water = 4184 J/(kg.degC)
energy = 30*10-6m3*1000kg/m3*4184J/(kg.degC)*(27-22)degC = 627.6 J
1 J is about 0.2389 calories so energy = 627.6*0.2389 ≈ 150 calories (Note these are not food calories. 1 food calorie is 1000 small calories)

thanks Alan :)
You know, if I wanted to know how many calories there are in a marshmellow, I'd probably just google it :/
Mmm, how boring would that be :)))
Ok Melody, here's the boring way: http://www.sparkpeople.com/calories-in.asp?food=marshmallow
The more interesting way would be to eat a marshmallow and measure your own temperature rise. As one marshmallow would undoubtedly produce a temperature rise too small to measure you would probably have to eat several bags of them. Have fun!
