See sample questions for grade 11
A beaker contains a mixture of ice and water at 0°C. If heat is supplied, what will happen to the temperature until all the ice melts?
A sample of water at 100°C is kept at atmospheric pressure. What state(s) of matter will be present?
Calculate the amount of heat required to convert 50 g of ice at 0°C to water at 0°C. (Latent heat of fusion of ice = 334 J/g)
Describe what happens to the arrangement and movement of particles during sublimation.
Describe what happens to the temperature of a substance during a phase change, such as melting or boiling.
Explain the difference between melting and freezing in terms of energy change and particle movement.
Explain why evaporation causes cooling.
Explain why pressure affects the boiling point of a liquid.
State the effect of increasing humidity on the rate of evaporation.
