Question: Where do students usually go wrong with specific heat capacity?
First of all you must memorise the equation!
Secondly, please note the following three most common mistakes that students making using this equation.
1.Not converting mass to kilograms, if it is not already in kilograms.
2.Not using the change in temperature; instead just grabbing the first temperature figure that they come across.
3.Not realizing that one of the temperatures may not be given as a number; for example, instead of being asked to heat water from 20oC to 100oC you might well be asked to heat the water from room temperature to boiling temperature.
