- Relative humidity is more than \( 60\% \).
- Relative humidity is less than \( 60\% \).
How do we feel about air in each of the following conditions?
- Relative humidity is more than \( 60\% \).
- Relative humidity is less than \( 60\% \).
Show Hint
Solution and Explanation
- When the relative humidity is more than \( 60\% \), the air feels more humid, and we may feel uncomfortable, especially in hot weather. Our body's ability to cool itself through evaporation (sweating) becomes less efficient, making us feel warmer than the actual temperature.
- When the relative humidity is less than \( 60\% \), the air feels drier. In such conditions, we may experience dryness in the skin, eyes, and throat, especially in extreme cases. Evaporation is more effective, and we may feel cooler than the actual temperature.
Relative humidity is the amount of water vapor present in the air compared to the maximum amount it can hold at a given temperature. - In high humidity (more than \( 60\% \)), the air retains more moisture, making it harder for sweat to evaporate, thus making us feel hotter and sticky. - In low humidity (less than \( 60\% \)), the air feels dry, and moisture evaporates more quickly from our skin, which can make us feel cooler but also potentially dehydrated.
Top Questions on Heat

- Heat (in calorie) required to increase the temperature from \( 10^\circ C \) to \( 20^\circ C \) of 6 kg copper is the same as the heat (in calorie) required to increase the temperature from \( 20^\circ C \) to \( 100^\circ C \) of 3 kg lead. If the specific heat of copper is 0.09, then the specific heat of lead will be:

- Appreciation of the poem:
Read the following poem and write an appreciation of it with the help of the points given below:
Stopping by Woods on a Snowy Evening
Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow
My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.
He gives his harness bells a shake
To ask if there is some mistake.
The only other sound’s the sweep
Of easy wind and downy flake.
The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\))
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
