States of matter Flashcards
What are the 3 states of matter?
Gas, Liquid and Solids
How is the particle model represented in the states of matter?
By small, solid spheres, that describes the arrangement, movement and energy of particles in a substance
What is the closeness of a solid, what is it’s arrangement of particles, moment of particles and energy of particles?
The closeness is very close, the arrangement of particles is a regular pattern, the movement of particles vibrate around a fixed position and it’s energy of particles is low
What is the closeness of a liquid, what is it’s arrangement of particles, moment of particles and energy of particles?
The closeness is close, the arrangement of particles is a randomly arranged, the movement of particles move around each other and it’s energy of particles is greater than energy
What is the closeness of a gas, what is it’s arrangement of particles, moment of particles and energy of particles?
The closeness is far apart, the arrangement of particles is a randomly arranged, the movement of particles move quickly in all directions and it’s energy of particles is the highest energy
States of matter, A single particle does not have the properties of the material it is part of. The properties of a substance are the properties of a huge number of particles together, True or False?
True
What is melting in States of Matter?
A solid melting into a liquid
What is freezing in States of Matter?
A liquid freezing into a solid
What is evaporation/ boiling in States of Matter?
Liquid evaporates/ boils into gas
What is condensing in States of Matter?
Gas condenses into a liquid
What is sublimation?
When some substances can change directly from solid to gas, or from gas to solid, without becoming a liquid in between
Every substance doesn’t have it’s own melting point and boiling point, True or False
False
