A chunk of metal has a mass of 600g and has been in boiling water for several minutes. It is quickly dropped into an insulating Styrofoam beaker containing 1.20 kg of water at room temperature (20.0°C). After waiting few minutes, you observe that the water's temperature has reached a constant value of 23.0 °C.
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.

a) Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat of the metal?
b) If the heat absorbed by the Styrofoam actually is not negligible, what would be the specific heat of the metal?
A)Greater than the one calculated in part (a).
B)Smaller than the one calculated in part (a).
C)Same as the one calculated in part (a).
