Ahow does matter change from one state to another?
b how is melting similar to solidification? how is it different?

A.Matter can change from one state to another if heated or cooled.

B.The difference is evaporation is a change from liquid to gas. ... Melting is similar to solidification because they both involve a part in being liquid and solid. They are different because melting is solid to liquid and solidification is liquid to solid.

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

but which class are u may know that first
