What is strong?
Condensing point is the same as
What is boiling point
Example of where diffusion occurs
Can Liquid be compressed?
What is no
The process in which a solid turns in a gas
What is Sublimation
As particles are exposed to colder temperatures they _____
The temperature of a substance is 345 degrees celsius, its boiling point is 2394 degrees celsius and its melting point is 203 degrees celsius. What state is it?
What is liquid
What is the particles eventually become evenly spread?
The particle model displays ...
What is a description of the arrangement of solids, liquids, and gases?
The difference between evaporation and boiling
What is evaporation is when the surface begins to change states from liquid to gas while boiling is when the entire liquid begins to change states from liquid to gas?
Particles in a _________ take the shape of the container.
What is liquid
Substance Z is -634 degrees Celcius. If its melting point is -523 degrees Celsius and boiling point is -235 degrees Celsius, what state is it?
What is Solid
What is a low concentrated area?
2 out of the 3 limitations of the particle model
What is the difference forces of attraction, different shapes and sizes, the space between them
Rain occurs because
Hint: What state is a cloud and what state would it have to change into to rain?
What is the water vapor in clouds condense into water droplets?
Explain what occurs in the particles when a gas turns into a liquid.
What is the particles lose energy, the particles begin to move and vibrate less around each other, and eventually, the bonds are reformed.
The normal melting point of oxygen is -218°C; its normal boiling point is -189°C. The temperature of oxygen currently is -124 degrees celsius, what substance is it?
What is gas?
Why does diffusion occur in liquids and gases but not in solids?
What is because it involves particles moving randomly, in solids the particles are tightly packed.
