Specific Heat Capacity
Physics ⇒ Heat and Thermodynamics
Specific Heat Capacity starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Specific Heat Capacity.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
