Heat Transfer by Convection

Explain thermal conduction, thermal convection and thermal radiation.

Heat reaches from the Sun to the Earth. Can thermal convection be used to transfer heat from the Sun? Explain. What are the main differences of radiation from other two modes?

Among the options, _____ (hot air / cold air) is denser.

The transfer of heat in liquids is by _____. 

Wind is produced due to _____.

In the convection method of heat transfer, the particles of the medium move from one place to another.

Amongst water, wind and vacuum, heat cannot flow due to convection in _____.

The convection currents in air results in sea breeze and land breeze.

Which mode of heat transfer causes the sea breeze and land breeze?

Radiation of heat takes place through _____.

The phenomenon of land breeze occurs during day time.

Name the camera which uses radiations to make our surroundings visible at night.

Which of these statements is true at night in a coastal area? 

Complete the answer.
I move from land to sea at night - ______ breeze.  

Name the following.
The breeze that moves from sea to land. (Sea breeze/Land breeze)

Give the reason for the formation of hot currents in the sea?

What is land breeze? What is sea breeze?  

In this question, the first and the last part of the passage are numbered ${\mathrm{S}}_1$ and ${\mathrm{S}}_2$_. The rest of the passage is split into four parts numbered $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and  $\mathrm{D}$. These four parts are not given in their proper order. Read the sentences and find out which of the four sequences is correct.
${\mathrm{S}}_1$: When the wind moves gently, it is called a breeze.
$\mathrm{A}$ : This cooler air begins to flow towards the land to occupy the space created near the land.
$\mathrm{B}$ : As compared to the land, sea-water takes longer to heat up. Therefore, the air adjacent to it is cooler.
$\mathrm{C}$ : The air adjacent to the land becomes warm. Warm air rises up.
$\mathrm{D}$ : During the day, due to the heat of the sun, land heats up quickly.
${\mathrm{S}}_2$: The wind that blows from the ocean towards the land is known as the sea breeze.

I am the wind blowing from the land towards the ocean. Who am I?

I am the wind blowing from the sea towards the land. Who am I?
