you've gotta check out 'uses' of it
then you will understand Why we need it

anonymous · Answer

calimeter is used to determine the delta H?

somy · Answer

yeah i guess :)

somy · Answer

it's pretty important to know right?
coz if u do know the amount of heat lost/gained 
u can change that according to your needs

anonymous · Answer

im still slightly lost in how it is used to cancel out the effects from the instrument?

somy · Answer

maybe you should watch some vids on how it is used?

anonymous · Answer

oh ok ... lastly is what is another method for calibrating a calorimeter without the use of a electric heater
i know one method is to use a ractant with a know delta H

anonymous · Answer

but how does that work? what formula do we use to find the calibration factor?

somy · Answer

tbh you are asking the wrong person since i have no idea lol but here are some vids on how is it used http://www.youtube.com/watch?v=yzmdV6UzzWk
