Interconversion of States of Matter starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Interconversion of States of Matter.
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 10
A sample of water at 100°C is being boiled at standard atmospheric pressure. What is the state of water during boiling?
A student heats a beaker of ice at 0°C. After some time, the temperature remains constant even though heat is still being supplied. Explain why.
A student observes that wet clothes dry faster on a windy day. Explain why.
Describe the effect of increasing pressure on the boiling point of a liquid.
A beaker contains 100 g of ice at 0°C. How much heat is required to completely melt the ice? (Given: Latent heat of fusion of ice = 334 J/g)
