Heat Transfer Mechanisms

Yes, it is the correct answer. The colour of the wire does not have any effect on the heat produced.

Yes, it is correct. Both the options are correct.

It refers to equal thermal anomaly of several places, and the lines drawn on the world map joining places of equal thermal anomaly are called isanomals.

Heat is a form of energy because heat is produced by the utilization of energy.

Conduction is the primary mode of heat transfer in solids.

Electricity is not a mode of heat transfer as it is a form of energy. It is the flow of electrons.

Tea is generally served in China clay cups as they are bad conductor of heat, that prevents the lips from heat of  tea, which is more sensitive than tongue.

Heat radiations from the furnace make one feel warm while standing beside its as the hot objects emit radiant energy. When falls on other objects, it is partially reflected and partly absorbed. The part that is absorbed increases the energy of the objects and makes one feel warm.

Materials which allow heat to flow through them are called good conductor of heat. For e.g. Copper and aluminium are good conductors of heat.

Copper is good conductor of heat as copper allows heat to pass through it and conducts heat faster.

Radiation is the form of heat transfer that can occur in the absence of a medium. Thus, it is possible to transfer heat in vacuum through the process of radiation.

Temperature is defined as the degree of hotness or coldness of a body.

When water is taken in a flask and is heated from the bottom then, by the process of convection, water gets heated in this experiment. When it is heated, the water near the flame becomes hot and this hot water rises up at the surface of the flask. The cold water from the sides moves down towards the source of heat and becomes hot and starts rising up. This process continues till the whole water gets heated. Thus, the heat is transferred to the entire volume of water through the movement of water molecules. This process of the hotter fluid moving and transferring heat to the colder surroundings is called convection.

The process of vertical heating of the atmosphere is known as convection. This is the correct answer.

The interaction of insolation with the atmosphere and the earth's surface creates heat which is measured in terms of temperature. This is the correct answer choice.
