Science Chap 3

Question Answer
What is viscosity? The resistance to flow
Is the viscosity of honey high or low High
Is the viscosity of water high or low Low
If more gas is added to a container is the pressure increased or decreased Increased since more is being added
If the size of the container increases does the pressure increase or decrease The pressure decreases because there is more space for molecules to go
The temperature of the gas goes up does the pressure increase or decrease Pressure increases because the temperature releases gases which takes up more space
If the temperature of gas goes down does the pressure increase or decrease The pressure decreases since there is becoming more space available
How does heat affect the viscosity It makes the resistance not as great
Describe the volume and shape in movement of particles for a solid Volume equals definiteShape equals definiteMovement of particles equals shiver in place
Describe the volume and shape in movement of particles for a liquid Volume equals definiteShape equals not definiteMovement of particles equal slide past one another
Describe the volume and shape and movement of particles of a gas Volume equals definiteShape equals not definite movement the particles equals move all around
When water is melting are the particles gaining or energy or losing energy Gaining
When water freezes are particles gaining energy or losing energy Losing
When water is evaporating are particles gaining energy or losing energy Gaining
When water is boiling are particles gaining energy or losing energy Gaining
When water condensates are particles losing energy or gaining energy Losing
What changes of state takes place when water is melting Solid to liquid
What changes of state takes place when water is freezing Liquid to solid
What changes of state takes place when water is evaporating Liquid to gas
What changes of state takes place when water is boiling Liquid to gas
What changes of state takes place when water is Condensating Gas to liquid
When water is melting a particle speeding up or slowing down Speeding up
When water is freezing are particles speeding up or slowing down Slowing down
When water is evaporating are particles speeding up or slowing down Speeding up
When water is boiling a particle speeding up or slowing down Speeding up
When Water is condensing are particles speeding up or slowing down Slowing down
What is Boyles law States that as the volume of gas changes so does it pressure( remember marshmallow experiment)
If the volume of a gas goes UP then the pressure ___. goes down
If the volume of a gas goes DOWN then the pressure ______. Goes up
What is Charles law States that as the temperature of a gas changes so does its volume
The temperature of a gas goes UP then the volume ______. Goes up
If the temperature of a gas goes DOWN then the volume________. Goes DOWN
What is sublimation Sometimes a substance changes directly from a solid to a gas or from a gas to solid
Are the freezing point and melting point the same Yes
What is surface tension The result of an inward Pulll among the molecules of a liquid that bring molecules on the surface closer together
Why does the surface of the pool feel hard Because the molecules are tightly packed together
What happens to the surface tension of water when you jump into the pool The market is broke which broke the surface tension
Why does the food come and just sit on the milk It didn't break the surface tension
what is matter Anything that has mass and takes up space
What is volume Amount of space matter takes up
What is chemistry The study of matter
Molecules tightly packed together they vibrate in place Solid(Remember in ice cube molecules are shivering in place)
Molecules can slide past each other Liquid(Remember they are excited)
Molecules are far apart and move freely to all parts of a container Gas(remember they want to be released)
