How much heat energy is required to raise the temperature of 0.367 kg of copper from 23.0 degrees C to 60.0 degrees C? The specific heat of copper is 0.0920 cal/(g*C)

Question

xishem · Answer

$$Q=cm \Delta T$$Where...
Q is the heat energy added.
c is the specific heat of the material
m is the mass of the material
T is the temperature

$$Q=(0.0920\frac{ Cal}{g*C})(0.367kg)(60.0C-23.0C)$$$$Q=1.249268\frac{Cal*kg}{g}*\frac{1000g}{1kg}*\frac{4.184J}{1Cal}=5226.94J$$Now to report it with the correct number of SFs...
$$5.23*10^3J$$
