(K-273)/100=C/100=(F-32)/180 So, (K-273)/100=25/100=(F-32)/180 => K= 298 => F= 77

Gaurav Seth 3 months ago

The normal room temperature which would be comfortable for living is around 20 - 25° C.

In chemistry, The upper limit 25°C is taken as Standard room temperature .

We know that,
Temperature on Celsius + 273 = Temperature on Kelvin.

Now,
25°C = 25 + 273 = 298K .

Therefore, The standard room temperature in Kelvin is 298 k

Isotonic Solution:

If the medium surrounding the cell is of exactly the same water concentration as inside the cell, there will be no net movement of water across membrane resulting in no change in size of cell. Such solution is called Isotonic solution.

(iii) Hypertonic solution:

If the medium surrounding the cell has a lower water concentration than inside the cell, i.e., if the solution is highly concentrated, then the cell will lose water through osmosis. Such concentrated solution is called Hypertonic solution.

Yogita Ingle 1 year, 3 months ago

Atoms and molecules are too small to count. To solve this problem their numbers are expressed in terms of Avogadro’s number (N_A = 6.023 10²³). Mole is the number equal to Avogadro’s number just like a dozen is equal to 12, a century means 100, a score means = 20.

Mole can be defined as a unit which represents 6.023 x10²³ particles of same matter.
