Specific Heat
The equation that can be used to determine how much heat is released or absorbed by water when a cheeto is burned in a calorimeter.
Q=m x Cp X ∆T
What unit is typically used to measure mass?
gram
The amount of energy needed to raise the temperature of 1 gram of a substance by 1 degree Celcius.
Specific Heat Capacity
This is the equation that can be used to solve for specific heat capacity.
Cp=Q/m x ∆T
