Answer 1

Answer:

1. When the balloon is kept in the sun, due to Sun's heat, the kinetic energy of gaseous particles inside the balloons also gets increased and the balloon expands. This will increase the pressure on the walls of the balloon. It continues to expand and comes to a stage when the balloon bursts.

2. At higher temperatures, particles have high kinetic energy and move faster hence, due to this smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you have to go close. Note: Particles of matters are continuously moving. They possess kinetic energy.

4. Functions of all the organelles are inter-linked to each other and ultimately to the working of the example cell. So, if even a single link is missing, the cell ultimately suffers and die.
