A student notices that water spilled on a table eventually disappears (evaporates) even though the room temperature is well below the boiling point of water.
State two ways in which evaporation differs from boiling.
This part of the question is about an experiment to determine the specific latent heat of fusion of ice.
Suggest apparatus that will provide thermal energy to melt the ice and state the readings needed to determine the amount of thermal energy provided.
Suggest apparatus required for determining the mass of ice melted (meltwater collected) and state the readings needed to determine that mass.
528 exam-style questions on CIE IGCSE Physics 2.2 Thermal properties and temperature, covering 2.2.1 Thermal expansion of solids, liquids and gases, 2.2.2a Internal energy and temperature, 2.2.2b Specific heat capacity, 2.2.3a Melting, boiling, condensation and solidification, 2.2.3b Evaporation, and 2.2.3c Cooling by evaporation. Each one has a worked solution and a mark scheme showing where the marks go.
