You finish making pudding.

Heat up starch in water
the starch molecules burst because of all the water it absorbs

A hydrogen bond is

the bond between the oxygen and hydrogen in one water molecule

the bond between oxygen and hydrogen in two different water molecules

the bond between two hydrogens in one water molecule

the bond between two hydrogen atoms in two different water molecules

Question 3
