States of Matter Flashcards
What are the three states of matter?
Solid, liquid, gas
Each state has distinct properties based on particle arrangement, movement, and energy.
How are the three states of matter interconverted?
Through processes such as melting, freezing, evaporation, condensation, sublimation, and deposition
These processes involve changes in particle arrangement, movement, and energy.
What is the definition of a solvent?
The substance that dissolves a solute
Common examples include water and alcohol.
What is the definition of a solute?
The substance that is dissolved in a solvent
Examples include salt and sugar.
What is a solution?
A homogeneous mixture of solute and solvent
Solutions can be in various forms, such as liquid, gas, or solid.
What is meant by a saturated solution?
A solution that cannot dissolve any more solute at a given temperature
Additional solute will remain undissolved.
What does solubility mean in the context of g per 100 g of solvent?
The maximum amount of solute that can dissolve in 100 g of solvent at a specific temperature
It is a measure of how well a solute dissolves.
What are the key components involved in experiments on dilution of coloured solutions?
Concentration, volume, and color intensity
Changes in these components help explain the results.
What are the key components involved in experiments on diffusion of gases?
Gas concentration, temperature, and particle size
These factors influence the rate and extent of diffusion.
How do you plot a solubility curve?
By graphing solubility (y-axis) against temperature (x-axis)
The curve shows how solubility changes with temperature.
What is the practical investigation to determine solubility of a solid?
Dissolve the solid in water at a specific temperature and measure the amount that dissolves
This helps understand solubility limits.
