Calorimetry Flashcards
1
Q
What is the equation for change in energy?
A
q = m x c x Δt
q = heat exchanged with surroundings (J) m = mass of substance heated or cooled (g) c = specific heat capacity (default to 4.18) Δt = change in temperature

Q
How to convert from ºc to Kelvin?
A
Add 273.
3
Q
How to find molar enthalpy change?
A
Divide energy by moles of substance.
4
Q
Why may the calculations be inaccurate?
A
The experiment may not have been carried out under standard conditions.
Heat may be lost to the surroundings.
