properties of substance

Question 1

Define matter as being made of particles that are continuously moving and interacting.

Answer 1

all sustances are made of tiny particlas that are constantly moving

particals are attracted toward eachother

they are contanly movign until they are colled to -273 degrees

thr hotter the sunstance th faster they more

Question 2

Classify matter as being solid, liquid or gas.

Answer 2

mater is something that takes up space and makes and is always moving. the further away simehting is and the more it vibrates/moves depends on what it it.

Question 3

Use a simple particle model to predict the effect of adding or removing heat on different states of matter.

Answer 3

adding heat turns solid into liquid and liguid into gass and cooling turns gass into a liguid , liguid into a solid

Question 4

Use the words evaporation, condensation, boiling, melting, solidification, sublimation and freezing to describe
physical changes that take place when matter changes state.

Answer 4

when a solids changes into a liquid it uses melting and when a liquid turns into a gas it is evaporation and when the liquid turns into a solid using freezing.
