in a chemical can be calculated using
system' the equation
Q = mcT Joules
Heat chance is just
Standard enthalpy has
the difference standard conditions
between the which are:
enthalpy of the A pressure of 100kPa

The particles are
dissolved in the
solution
The heat is
exchanged from the
particles into the
solution
The heat exchange is
measured using the
thermometer
There are limitations
in using a simple
calorimeter which
