Measuring heat energy
● ***Specific heat capacity (s.h.c. [J/kg ˚C]): amount of energy required to increase
temperature of 1 kg of substance by 1˚C
● Different substances need different amounts of heat energy to cause same increase
in temperature; factors depend on:
○ Difference in temperature (between object & environment)
○ Specific heat capacity of material the object is made from
● ***
Δ Q( change∈thermal energy [J ])=m(mass[kg ])∗c (specific heat capacity )∗Δ T ( change∈temperatur
