Bomb Calorimeter Calculation

Postby elizabethrojas1G » Thu Jan 21, 2016 8:28 pm

What do each of the variables mean in the equation qP= delta H = gCsp delta T?
Also, is a bomb calorimeter closed or isolated? Is it always the same case?

qP refers to the heat transfer at constant pressure
delta H refers to the change in enthalpy of the system
g * Csp * delta T refers to the (grams of a substance) * (the specific heat) * (the change in temperature)

because heat can be transferred I think a bomb calorimeter is considered a closed system and not an isolated system

Hope this helps

*Correction
A bomb calorimeter is considered an isolated system because the heat does not come form the surroundings but from the system itself.

Sorry about the initial wrong explanation.
