Question

The amount of heat needed to change the temperature of an object can be calculated using the
following equation:
Q = m c p Δ T 
where
Q = amount of heat in calories
m = mass of object in grams
c p = specific heat of object
Δ T = change in temperature in ∘ C 

What is the appropriate unit for c p  if the preceding equation is to be homogeneous in units?
