Water kept in a black pot will cool faster because blackened surface is a good radiator than a silvered surface.

Dark coloured clothes absorb more heat and, therefore, we prefer to wear dark coloured clothes in winter. On the other hand light coloured clothes reflect most of the heat that falls on them. Therefore, we prefer to wear light coloured clothes in summer.

Two thin woollen blankets shall be warmer than a thick woollen blanket because more air is trapped between the two thin blankets than a single woollen blanket. Air is a poor conductor of heat and does not allow the heat to pass from the body.

A clinical thermometer consists of a long narrow, uniform glass tube. It has a bulb at one end which contains shining liquid mercury. Outside the bulb a small thread can be seen in which mercury can flow. It has scale marked from 35°C to 42°C.

In Celsius scale, the temperature at which pure water freezes at sea level is taken as the lower fixed point whereas, the temperature at which pure water boils at sea level is taken as the upper fixed point. The lower and upper fixed points are marked as 0⁰C and 100°Crespectively. The scale between these points is then divided into 100 parts.

Clinical thermometer: It is used to measure the body temperature of a human body. The scale on its stem shows temperature from- 35°C to 43°C. It has a slight 'bent' or 'kink' in the capillary tube just above the bulb.
Laboratory thermometer: It is used to measure the temperature of different objects in the laboratory. The scale on its stem shows temperature from 10°C to 110°C. A laboratory thermometer is bigger in size than clinical thermometer and kept upright and not tilted when making measurement.

The molecules of solid are held strongly due to intermolecular forces and thus cannot move from one place to another place of the solid. So, convection is not possible in solids.

Jerks are given to clinical thermometer before using it to settle down the mercury level below normal temperature so that the measurement taken of a body be accurate.

It is advised not to hold the thermometer bulb while reading it as the level of mercury increases from the actual reading by our body temperature.

In case of two thin blankets, there is an air gap which does not allow heat pass out from the body and it is not as such as in case of one thick blanket.

Radiation is the mode of transfer of heat in which medium is not required.

Window should preferably towards the sea beach so that the sea breeze coming from sea keeps the house cool during the day time.

Since, the black bodies are better radiators, so due to this reason, radiators in cars are painted black.

As we know that jute sacks is thermal insulators, it helps ice not to be melt immediately. So, shopkeepers used to cover ice blocks with jute sacks.

As the temperature increases, then expansion in mercury takes place which leads to the rise in the level of mercury in thermometer.
