Explanation

Nitrogen gas is used in chips packets because it controls the Oxygen reactivity

Explanation

Water is known to have a higher specific heat capacity which makes it an ideal coolant.

This is because coolant is used to regulate heat in a device

and in order to regulate heat, the coolant must be able to tolerate high levels of heat,

so this is done by water due to its high specific heat.

Explanation

A molecule is the smallest unit of a compound

that can exist by itself and retain all of its chemical properties.

while

 An atom is the smallest particle of matter

Explanation

Clay is a poor conductor of heat as compared to wood and bricks.

Therefore, clay neither allows the external heat to enter the house in summer nor allows the internal heat to escape in winter.

Hence, mud houses remain colder in summer and warmer in winter.

Explanation

Explanation

Steam has higher energy than boiling water because it possesses the additional latent heat of vaporization.

So, when steam falls on the skin and condenses to produce water it gives out 22.5 x 105 J/kg more heat than boiling water at the same temperature.

Explanation

According to Newton's third law of motion, air strikes the wings in opposite directions.

When a bird is flying, the bird pushes the air with its feather in the backward direction (action),

and the air, in turn, pushes them forward due to the force of reaction.

Explanation

Someone who is dilatory makes a habit of delay; someone who is menacing frequently offers threats.
