Multiple choice physics transfer of heat applications of heat conduction applications of insulation clothes - our necessity

Why do we wear cotton clothes in Summer ?

  1. Cotton is a bad conductor of heat and doesn't allow passage of warmer air near body.

  2. Cotton is a good conductor of heat and allows body heat to escape in the atmosphere.

  3. Cotton absorbs sweat from the body, exposing it to atmosphere for easy evaporation

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

We wear cotton clothes during summer as cotton absorbs sweat from the body, exposing to the atmosphere for easy evaporation. As we tend to sweat more during summer and cotton fabric absorbs sweat and help body to cool down. Cotton allows better air circulation which helps to absorb and removing body moisture caused by sweat via evaporation.

Multiple choice physics transfer of heat applications of heat conduction applications of insulation clothes - our necessity

Wool is used in making garments used in winter because

  1. Wool is a good conductor of heat

  2. Wool is a bad conductor of heat

  3. Air, trapped in between the wool fibres, prevents the flow of heat from our body to the cold surroundings.

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wool is used in making garments used in winter because wool is bad conductor of heat; it insulates the body from the surrounding. And the air which is trapped in between the wool fibers; prevents the flow of heat from our body to the cool surrounding. As air is the bad conductor of heat too it also insulates the body with wool.

Which of the following fabrics is preferred for winter garments ?

  1. Nylon

  2. Cotton

  3. Wool

  4. Silk
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Wool is the fabric that is preferred for winter garments. As wool is bad conductor of heat. It insulates the body from the surrounding. And the air which is trapped in between the wool fibers; it prevents the flow of heat from our body to cool surrounding.

Multiple choice physics transfer of heat applications of heat conduction applications of insulation clothes - our necessity

Which of the following is not a reason for using woolen clothes in Winter ?

  1. Wool is an insulator of heat.

  2. It traps a layer of air in its fabric.

  3. Air being an insulator doesn't allow body heat to escape into the atmosphere.

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Reason behind using woolen clothes during winter is that wool is the bad conductor of heat, it insulates the body from the surrounding. And the air which is trapped between woolen fabrics, prevents the flow of heat from the body as air is a bad conductor of heat too. So as a result the heat present in the body remains trapped in the body, it can't escape to atmosphere.

Multiple choice botany reproductive morphology significance of fruits fruit plants: structure and function

Starch grain in latex are

  1. Elongated

  2. Oval

  3. Dumbell shaped

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Starch is an insoluble polysaccharide which is formed by the condensation of glucose. Starch is present in many plants in storage tissue. They are found in various shapes and may be used for identification of plants. 
Starch is present in latex in dumbell or rod shaped. 
Thus, the correct answer is option C.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The most fibre are chemically composed of non-starch polysaccharides like cellulose, inulin, lignin, chitins, pectins, oligosaccharides. They are either obtained from plants or animals. They are either soluble or insoluble. 

Multiple choice chemistry substances in daily use rayon and nylon synthetic fibres synthetic fibres or threads polyester and acrylic

Bed sheets are made up of:

  1. rayon and wool

  2. rayon and plastic

  3. rayon and nylon

  4. rayon and cotton
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bedsheets are made by blended fibre i.e. a mixture of rayon and cotton. Rayon is a versatile fibre and is widely claimed to have the same comfort properties as natural fibres, although the drape and slipperiness of rayon textiles are often more like nylon. It can imitate the feel and texture of silk, wool, cotton and linen. The fibres are easily dyed in a wide range of colours.

Which of the following is a disadvantage of nylon?

  1. They do not shrink

  2. They are less resistant to sun light

  3. They are resistant to insects and molds

  4. They can be easily dyed
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nylon fabrics have low resistance to sunlight. 


They are not suitable for curtains or draperies as it is weakened by the exposure to sunlight.

Hence the correct option is B.
