The diagram shows changes of state between solid, liquid, and gas. the atoms of a substance gain energy during a change of state. before the change, the atoms are close together and cannot slide past one another. after the change, the substance can fill its container.

which arrow represents the change of state described above?

l
m
n
o

Answer is: L.

The process by which a solid changes directly to a gas without first becoming a liquid is called sublimation.

Sublimation is an endothermic process.

For example dry ice (carbon(IV) oxide in solid state) is used because of sublimation in nightclubs, fog machines, at theaters, haunted house attractions .

1) Gas: does not have a definite shape or volume and changes to liquid on cooling.

2) Liquid: has definite volume but not shape and changes to solid on cooling.

3) Solid: has definite shape and volume and changes to liquid on heating.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
