You can tell if work is being done on an object by observing if there is a change in the object's energy. Work is done when a force is applied to an object, causing it to move in the direction of the force. This movement results in a transfer of energy to the object, indicating that work is being done.
Yes, work can be done by friction. When an object moves against a surface due to friction, work is done to overcome the resistance offered by the frictional force. This work results in heat production and can cause the object to experience a change in its kinetic energy.
Two examples of fine solids include flour and powdered sugar. These substances have very small particle sizes, making them ideal for use in baking and cooking to create smooth textures.
Millions of people all over the world...could you possibly tell us what the specific work you want to know about is?
This is one way that you can tell if the egg is raw or hard-boiled. A hard-boiled egg has solid interior of fairly consistent density so it will just spin. But a raw egg has the semi-solid yolk material which floats around in the fluid. When you spin the raw egg, the yolk will move to try to get to the outside of the circle, like if you were to spin a yo-yo around at the end of its string. Since one end is now heavier than the other, the egg will wobble and cannot maintain the spin, and soon comes to a halt. So if you are packing a picnic basket or lunchbox, you do not want to put a raw egg in, or you will be in for a surprise when you go to peel off the shell.

You can tell scrambled eggs are done cooking when they are no longer runny and have a firm, but still moist, texture.
You can tell when pasta is done cooking by tasting it. It should be tender but still slightly firm, known as "al dente."
