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
A 0.1 kg sample of a substance requires 420 J to increase its temperature by 2 K. What is its specific heat capacity?
A 0.2 kg sample of a substance is heated from 30°C to 80°C using 3000 J of energy. Calculate its specific heat capacity.
A 0.5 kg sample of a substance requires 1000 J of heat to increase its temperature by 4 K. What is its specific heat capacity?
A 1 kg block of copper (specific heat capacity = 390 J/kg·K) is heated from 20°C to 50°C. How much heat is required?
A 1 kg sample of a substance at 20°C absorbs 2000 J of heat and its temperature rises to 30°C. What is its specific heat capacity?
A 250 g piece of metal at 100°C is placed in 100 g of water at 20°C. If the final temperature is 25°C, and the specific heat capacity of water is 4200 J/kg·K, calculate the heat lost by the metal.
