Explanation:

• Refrigerators - The fundamental reason for having a refrigerator is to keep food cold. Low temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria so that it takes longer for the bacteria to spoil the food.

• Work - Work is defined as a force acting upon an object to cause a displacement. It is expressed as the product of force and displacement in the direction of force. SI unit of work is Joule.

• Amber - When an amber is rubbed against a rod along with a piece of cloth, the amber attracts the small piece of dust. A glass rod, a plastic rod, or a hard rubber when rubbed against a cloth, display amber effect which is commonly known as static electricity. Electricity is caused due to electrons.

• Flower - A carpel is the innermost part of a flower. It is usually surrounded by male reproductive structures called stamens, both of which are surrounded by petals.
