1
Q
what is stoichiometry used for
A
can be used to convert masses of fuels to masses of other reactants and products in combustion equations
2
Q
A fuel or food’s heat of combustion can be estimated by
A
determining the change in temperature of water when the fuel or food is combusted below it.
3
Q
what is a calorimeter
A
insulated vessel designed to minimise and account for heat loss
4
Q
shc is
A
energy (J) required to raise the temperature of 1 gram of a given
substance by 1 °C
5
Q
calibration factor is
A
amount of energy (in J or kJ) required to be released/absorbed in a
given calorimeter to increase/decrease water temperature by 1 °C
