Question

In a closed flask of one litre,2.0 g of hydrogen gas is heated from 272°c to 327°c. Which of the following is incorrect?​

Answer 1

Answer:

i guess these are the options :

a) Pressure of the gas increases

(b) The rate of collision increases

(c) The number of moles of gas increases

(d) The energy of gaseous molecules increases.

Explanation:

Correct option is C  

The number of moles of the gas increases

The statement (C) is not correct.

(A) The rate of collision increases. With increase in the temperature, the rate of collision increases.

(B ) The energy of gaseous molecules increases.  With increase in the temperature, the energy of gaseous molecules.

(C) The number of mole of the gas remains unchanged.  It is independent of temperature as mass is independent of temperature.
