Answer:
a)Because of the random movement of potassium permanganate particles, a dense purple solution forms in water at base of the beaker. The purple solution will slowly spread into the rest of the water throughout the beaker creating a less dense but evenly colored purple solution.
b)rising rice
c)Bunsen burner,A bunsen burner is placed under one end. Very soon the other end becomes warm; its temperature rises. This can be detected simply by feeling the end of the rod. Heat has been passed down the rod by conduction.

Answer:
Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy. To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system.
