Particles Flashcards
On a hot day, explain the particles in a balloon
More energy, move quickly causing the balloon to pop
Explain the particles in a balloon on a cold day
Less energy, move slowly causing the balloon to shrink
Explain the following:
A) How a solid gets to a liquid
B) How a liquid gets to a gas
C) how a Gas gets to a liquid
A) melt
B) evaporate
C) condensate
Particles never…..
Disappear
In a substance what is the same
Every particle
Define density
The degree of compactness of a substance
Define the different points of melting, freezing and evaporating
Melting, freezing and evaporating points are the temperatures a substance melts, freezes and evaporates
A substance can only boil when….
Enough energy is in the particles
Define diffusion
When particles travel from an area of high concentration to an area of low concentration
What 3 things change the speed of diffusion
Size. State. Temperature
Particles are powered by
Energy
Higher the temperature
Higher the air pressie
