Calibration Factor Flashcards
1
Q
what is a calibration factor
A
The exact amount of energy released or absorbed during a chemical reaction
2
Q
equation for energy in terms of voltage, current and time
A
E = vit
3
Q
equation for calibration factor
A
CF = vit / ΔT
4
Q
equation for energy change
A
E = CF x ΔT
5
Q
when must the CF be established
A
before determining enthalpy change (at beginning of experiment)
6
Q
what are the units for CF
A
Joules per degrees Celsius
7
Q
how to find CF
A
determine how much energy is required to change temp of water by 1 degree
8
Q
what is a factor that must be accounted for when determining CF
A
energy loss to environment
9
Q
how can energy loss to environment be prevented
A
use an insulated container
10
Q
what is a ‘rule’ involving volume that must be followed
A
use a fixed amount of liquid in each experiment
