Paper 1 - States of Matter Flashcards
How is a substance classified as a compound?
Made up of 2 or more elements in a fixed ratio, chemically bonded to each other
How is a substance classified as a mixture?
Made up of 2 or more different elements not chemically bonded
How is a substance classified as an element?
The molecule only contains atoms of the same element
What is a saturated solution?
A solution in which no more solute can be dissolved without a change in solvent volume or solvent temperature
What is a solution?
A homogenous mixture of solute and solvent
What is a solute?
The substance that is dissolved in the solvent
What is a solvent?
The substance that dissolves the solute
How does a substance deposit?
- Substance cools down
- The particles have less kinetic energy so move around less rapidly and randomly
How does a substance freeze?
- Substance cools down
- The particles have less kinetic energy so move around less rapidly and randomly
How does a substance deposit?
- Substance cools down
- The particles have less kinetic energy so move around less rapidly and randomly
How does a substance melt?
- Particles gain kinetic energy and move around more rapidly and randomly
- Particles have enough energy to overcome the intermolecular forces
How does a substance evaporate?
- Particles gain kinetic energy and move around more rapidly and randomly
- Particles have enough energy to overcome the intermolecular forces
How does a substance sublimate?
- Particles gain kinetic energy and move around more rapidly and randomly
- Particles have enough energy to overcome the intermolecular forces
