Question

Use the particle theory of matter to explain why hot chocolate powder dissolves more rapidly in hot water than in cold water

Answer 1

because heat increases energy of the particles, making them move faster, thus making them collide faster...which makes it mix quicker and more efficiently

Answer 2

Step-by-step explanation:

The increase in temperature associated with heat increases the rate at which the hot chocolate dissolves.

This heat breaks apart the molecules holding the powder at a rapid rate compared to that of a cold water which is much slower.
