Physical Properties of Solids Liquids and Gases 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 Physical Properties of Solids Liquids and Gases.
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
A liquid has a density of 1.2 g/cm³ and a mass of 24 g. What is its volume?
A sample of gas is compressed at constant temperature. What happens to its density?
Describe the difference between crystalline and amorphous solids.
Describe the process of diffusion in gases with an example.
Explain the term 'surface tension' in liquids.
Explain why gases are highly compressible compared to solids and liquids.
Explain why gases have neither definite shape nor definite volume.
Explain why liquids can flow but solids cannot.
Explain why solids generally have higher densities than liquids and gases.
Explain why the boiling point of a liquid increases with an increase in external pressure.
A gas occupies 2.0 L at 300 K and 1.0 atm. If the temperature is increased to 600 K and the pressure is increased to 2.0 atm, what will be the new volume of the gas, assuming ideal behavior?
A sample of a crystalline solid is heated from 20 °C to 120 °C. Its temperature remains constant at 80 °C for several minutes before rising again. What physical process is occurring at 80 °C?
Describe how the physical properties of solids, liquids, and gases are influenced by the strength of intermolecular forces present in each state.
Explain why the enthalpy of vaporization of water is much higher than its enthalpy of fusion, relating your answer to the physical properties of liquids and solids.
