Question 1
The two particles A and B have de-Broglie wavelengths 1 nm and 5 nm respectively. If mass of A is four times the mass of B, the ratio of kinetic energy of A and B would be
Question 2
In Vander Waals equation of state of the gas law, the constant ‘b’ is a measure of
Question 3
For two gases, A and B with molecular weights MA and MB, it is observed that at a certain temperature, T, the mean speed of A is equal to the root mean square speed of B. Thus the mean speed of A can be made equal to the mean speed of B, if
Question 4
Accroding to the kinetic theory of gases, in an ideal gas, between two successive colisions a gas molecule travels:
Question 5
Temperature (in K) at which most probable speed of O2 becomes equal to root mean square speed of N2 is - [Given: N2 at 427 ºC]
Question 6
To a given container having a pore of definite size, gas A (mol. wt = 81) is filled till the final pressure become 10 atm. It was seen in 50 minutes 10 gm of A was effused out. Now the container was completely evacuated and filled with gas B (mol. wt = 100) till the final pressure become 20 atm. In 75 minutes how many gm of B will be effused out?
Question 7
Which of the following satisfies the greater compressibility of real gas?
Question 8
N2 + 3H2→2NH3. 1 mol N2 and 4 mol H2 are taken in 15 L flask at 27 °C. After complete conversion of N2 into NH3, 5 L of H2O is added. Pressure set up in the flask is -
