a-lining up next to each other

b-huddling around each other for the ball

c-running randomly in all directions

d-slowly jumping up and down in their places

a- state a = air; state b = neon

b-state a = water; state b = number cube

c-state a = water; state b = oxygen

d-state a = piece of metal; state b = air

a-the frog can change back into a tadpole.

b-the tadpole changes its shape and form.

c-the frog is made up of a different set of elements than the tadpole.

d-many reactions take place inside the tadpole as it changes into a frog.

a-250 g, mass remains same during physical change of freezing

b-500 g, mass of ice is twice the mass of juice

c-250 g, mass is conserved when matter is destroyed to form ice

d-200 g, mass of frozen liquid is less than mass of the original liquid
