In a calorimetry experiment, a 60 g metal sample was heated to 100°C, and then quickly transferred to a styrofoam cup with cover and containing 100 g of water at room temperature (23°C). After carefully swirling the calorimeter, the final temperature of the water was recorded at 27°C. Calculate for the specific heat capacity (Cm) of the metal sample. Assume that the specific heat capacity of water (Cw) is 1 cal/g-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.
In a calorimetry experiment, a 60 g metal sample was
heated to 100oC, and then quickly transferred to a
styrofoam cup with cover and containing 100 g of water
at room temperature (23oC). After carefully swirling the
calorimeter, the final temperature of the water was
recorded at 27oC. Calculate for the specific heat capacity
(cm) of the metal sample. Assume that the specific heat
capacity of water (cw) is 1 cal/g∙Co.
