Physics

Steam will produce more severe burns than boiling of water because steam has more heat energy than water due to its latent heat of vaporisation and additionally latent heat of condensation.

The most electrically conductive metal is silver.

In order to make an electromagnet you need a dry cell batteries, thin coated copper wire and iron nail.

A galvanometer is converted into a voltmeter by connecting with high resistance.

Tensional forces normally cause normal faults.

Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

The shape of our milky way galaxy is spiral.

According to Newton, force can never occur singly in nature; it is the mutual interaction between two bodies. This formed the basis of Newton’s Third Law of motion which states: “To every action, there is always an equal and opposite reaction.” Forces always occur in pairs.

It is easier to carry two buckets of water in one hand each, than to carry only one in one hand because the centre of gravity and centre of equillibrium fall within the feet. The weight is spaced out more evenly on both the sides of the body than it would be if you had to carry in a single bucket.

Red light suffers the least amount of deviation and violet the most. When a white light is made to pass through a prism, formation of a spectrum of seven colors occurs showing white light is a combination of seven separate colors.
