11
Q
use the calculated temperature change and mass and energy change to find…
A
specific heat capacity
12
Q
why may the result be inaccurate?
A
thermal energy lost into the air - use insulator that does not conduct heat
incorrectly reading thermometer - using electric probe
thermal energy not spread through the oil - stir the oil
