A solid.
Jello is considered a solid for the most part, before it is refrigerated it would be considered a liquid.
A solid is a fairly hard surface. But, not always hard; for instance jello, pudding. Simply it's not a gas or a liquid.
You can not swim in jello. It is too solid.
its a newtonian fluid it is also considered to be both solid and liquid or what is known as plasma. Other types of plasma are blood and volcanic magma and toothpaste and glue.
yes.
Jello
Yes, dry jello is still considered matter. (Its a solid if it keeps it shape)
A solid.
Of course, for example... Imagine a glass container or maybe a cup. The glass cup is a solid and it could contain liquids in that matter. Also if it's a solid but does not contain a liquid or gas it could still move... Jello is a solid but it still moves.
If this is the question you are asking, I am pretty sure Jello is a solid. Hope that helps!
You put it in the feezer
