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 12
Describe a method to experimentally determine the specific heat capacity of a solid.
Describe the difference between specific heat capacity and heat capacity.
Explain why coastal areas have milder climates compared to inland areas, in terms of specific heat capacity.
Explain why substances with low specific heat capacities are used for making cooking utensils.
A 0.2 kg piece of metal at 150°C is dropped into 0.5 kg of water at 20°C. The final temperature is 22°C. If the specific heat capacity of water is 4200 J kg⁻¹ K⁻¹, calculate the specific heat capacity of the metal. (Assume no heat loss.)
A 0.5 kg sample of a metal at 100°C is placed in 1 kg of water at 20°C. The final temperature of the mixture is 22°C. If the specific heat capacity of water is 4200 J kg⁻¹ K⁻¹, calculate the specific heat capacity of the metal. (Assume no heat loss to surroundings.)
A 1 kg block of a material at 25°C absorbs 2000 J of heat and its temperature rises to 35°C. What is the specific heat capacity of the material?
A 2 kg block of copper is heated from 20°C to 70°C. If the specific heat capacity of copper is 390 J kg⁻¹ K⁻¹, calculate the heat energy absorbed by the block.
