how did you know gas formed in your lava lamp experiment
because bubbles formed when we added the acid tablet

how did we measure density in the 1 lab we did in class
we calculated the volume and weighed our mass
200
what is a substance and give 1 example
what is volume
matter that has the same property throughout it
ex: sand
volume is the amount of space an object or material occupies
300
order the following in order of most dense to least dense.
oil
water
boiled egg

water
oil

i take the shape of a container, my particles are organized and stay together, i don't change my shape without an act of force what am i
solid
300
true or false or it depends
mixing can affect the properties of a substance
it depends because mixing a salad no changes happen but mixing sugar and water you can taste the change but you can't see it
300
our ublec lab is a mixture a solution or both
both
300
volume, density and mass are all examples of what
a physical property
400
ice is more dense than oil
ice is less dense than water and salt

give me 1 characteristic of each phase of matter
to discuss in class

what is the difference between a physical state and a physical property
a physical state is a form of matter such as solid liquid gas
a physical property is a characteristic of matter that you can observe
500
what is the difference between an insulator and a conductor?
a conductor is a material that electrical or thermal energy can move through.
a insulator is a material that electrical or thermal energy cannot move easily.

can water be a solid liquid and gas
explain
yes it can be frozen then its a solid when it melts it turns into a liquid and you boil it tuns to steam which is a gas
500
explain this reasoning...
"All solutions are mixtures, but not all mixtures are solutions"
not all mixtures can be dissolved but a solution is when 2 substances dissolve into each other
500
what is a particle and what is similar about solid and liquid particles
particles are tiny parts that make up matter
both solid and liquid particle are close together but a solid particle does not move but a liquid particle moves a little bit
