Phases of matter
What are the 3 phases of matter?
Liquid, solid, gas
a phase change with no temperature change
Latent Heat
Why can bugs walk on water?
Surface tension
amount of force acting on an object
pressure
Have a Definite Shape, Size, and Volume
Solid
changes the substance chemically Ex: burning paper
Chemical Change
2 different molecules stick together Ex: penny and water droplets
Adhesion
Alka Seltzer Rocket as ______ increases the ______increases
as volume increases the pressure increases
The Alka Seltzer built up pressure and had nowhere to go so it exploded
Have a Definite Size and Volume but NO definite Shape- takes the shape of its container
Liquid
does not change the substance chemically Ex: Ripping Paper
physical change
2 of the same molecules stick together Ex: water droplets sticking together
Cohesion
Marshmallow as _____ increases the ____(size) increases
as temperature increases the volume (size) increases
he marshmallow got bigger because it got warm in the microwave
Have NO Definite Shape, Size, or Volume
Gas
What temperature does water freeze at?
0 degrees Celsius
the upward force a fluid exerts on an object Ex: squeezing the bottle to make the diver move
Buoyant force
Balloon as _____ increases the_____ increases
temperature increases the pressure increases
Heating the cylinder made the pressure in the balloon build.
Pressure is greater in a smaller balloon than a bigger balloon.
Anything that has mass and volume- takes up space
Matter
What temperature does water boil at?
100 degrees Celsius
looks like a little dome or bubble on top of a cup of water
Surface tension
Bonus: What happened when a drop of soap was added to a full cup of water?
The chemicals in the soap broke the surface tension and made the water overflow
