how close are the particles in a solid
packed closely
how close are the particles in a liquid
still close together but not as packed as the particles in a solid
how close are the particles in a gas
far apart
how are the particles arranged in a solid
they are in a regular arrangement
how are the particles arranged in a liquid
they are in a random arrangement
how are the particles arranged in a gas
they are in a random arrangement
how do the particles move in a solid
vibrate in a fixed position
how do the particles move in a liquid
moves freely but slides over eachother
how do the particles move in a gas
move freely and fast
can a liquid flow
it can flow
can a solid flow
it cannot flow
can a gas flow
it can flow
is the volume of a solid fixed
yes it is fixed
is the volume of a liquid fixed
yes but it takes the shape of a container
is the volume of a gas fixed
no it is not fixed
is the degree of attraction strong in a solid
yes it is strong
is the degree of attraction strong in a liquid
no it is weak
is the degree of attraction strong in a gas
no it is very weak
The Kinetic Theory explains the properties of matter in terms of the arrangement and movement of particles.
Nitrogen is a gas at room temperature. Nitrogen molecules, Na, Which are spread far apart move in a random manner at high speed.
How does the movement and arrangement of the molecules in a crystal of nitrogen
differ from those in gaseous nitrogen?
The arrangement of the molecules in a crystal nitrogen are in a fixed arrangement meaning that the particles can only vibrate in a fixed position. While the molecules in the gaseous nitrogen is in a random arrangement and the particles move freely and fast.
