http://chemistry.elmhurst.edu/demos/DisappearingCup.html WebThe amount of energy (Q) transferred to the water can be calculated by using the equation Qw = mwCΔT w since the mass (m) and ∆T (temp change) can be measured. This allows for a calculation of the C value for the metal since the head gained (Qw) of the water will equal the heat lost by the metal (Qm).
WebThese easy-to-use “coffee cup” calorimeters allow more heat exchange with their surroundings, and therefore produce less accurate energy values. Figure 2.8.2: A simple calorimeter can be constructed from two polystyrene cups. A thermometer and stirrer extend through the cover into the reaction mixture. WebThis is a useful class experiment to introduce energy changes in chemical reactions, suitable for 11–14 and 14–16 year olds. Students measure the temperature changes in different reactions taking place in a polystyrene cup, classifying the reactions as exothermic or endothermic. The experiments can also be used to revise different types of ...
