Answer: please see anbswer below
Explanation:
She made such prediction because When food colouring is added into hot water, the difussion ie spreading rate will be fast . This is due to the high kinetic energy of of the molecules which are randomly bouncing against each other causing the solution to mix faster.
When compared with water at room temperature and cold water, the particles are not moving as fast and the food coloring does not spread or diffuse as fast as the hot water because of the lower kinetic energy of molecules in the warm and cold water although the food coloring in warm water will spread faster than in the cold water.
<span>Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5% or 35 parts per thousand. This means that for every 1 liter (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.

Neurons contribution MASS to the atom but not Charge to the nucleus !!
Answer:
Number of neutrons in the nucleus.
Explanation:
Mass number is protons plus neutrons. Protons do not change from isotope to isotope
