Physics

In electrical industries mica is used as a raw material.

The 1st law of thermodynamics states that internal energy change of a system equals net heat transfer minus net work done by the system.

Ohm’s law is valid in case of conductor.

In this case air blown by the fan will try to push the sail boat in a certain direction. But at the same time due to Newton’s third law of motion the fan will experience a force due to the air blown in a direction opposite to the direction in which the sail boat will experience the force due to the blown air. So, as a whole the system will be at rest and it will not move.

If ice floating on water in a vessel melts, the water level in the vessel does not change.

An ideal gas have no intermolecular force of attraction, so it cannot be liquefied by applying high pressure and decreasing temperature.
