HEAT AND THERMAL ENERGY: The Calorimeter

The process of accurately determining the specific heat capacity ( c ) of a substance is dependent upon minimal heat ( Q ) losses occurring within a system’s frame of reference. A calorimeter is designed so that such losses are negligible to the extent that they can be ignored. Consider the diagram below: A thinContinue reading “HEAT AND THERMAL ENERGY: The Calorimeter”

HEAT AND THERMAL ENERGY: Specific Heat Capacity Determination

Q: A quantity of lead shots weighing 100 g are placed in a beaker full of boiling water.  After the shots reach a temperature of 100.0 ℃, they are transferred to a vessel that contains 100 g of water at 20.0 ℃. After sitting for some time, the water cools to an equilibrium temperature ofContinue reading “HEAT AND THERMAL ENERGY: Specific Heat Capacity Determination”

HEAT AND THERMAL ENERGY: Specific Heat vs. Specific Heat Capacity

Although similar, the terms “ specific heat “ and “ specific heat capacity “ are not synonymous. Different materials have different abilities to absorb and store heat energy ( J ). Specific heat capacity refers to the amount of heat energy needed to raise 1 kilogram ( kg ) of a specific substance by 1Continue reading “HEAT AND THERMAL ENERGY: Specific Heat vs. Specific Heat Capacity”
