## STATES OF MATTER QUIZ-6

IIT JEE exam which consists of JEE Main and JEE Advanced is one of the most important entrance exams for engineering aspirants. The exam is held for candidates who are aspiring to pursue a career in the field of engineering and technical studies. Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.

Q1. At what temperature will the molar kinetic energy of 0.3 mol of ‘He’ be the same as that of 0.4 mol of argon at 400 K?
•  700 K
•  500 K
•  800 K
•  400 K
Solution:
Q2. Among the plots of P vs V, as given below, which one corresponds to Boyle’s law?
Solution:
Q3.  A balloon filled with ethyne is pricked with a sharp point and quickly dropped in a tank of H2 gas under identical conditions. After a while the balloon will
•  Shrink
•  Enlarge
•  Completely collapse
•  Remain unchanged in size
Solution:
Q4.  At what temperature will hydrogen molecules have the same KE as nitrogen molecules at 280 K?
•  280 K
•  40 K
•  400 K
•  50 K
Solution:
Q5.According to kinetic theory of gases, for a diatomic molecule
•  The pressure exerted by the gas is proportional to the mean velocity of the molecules
•  The pressure exerted by the gas is proportional to the root mean square velocity of the molecules
•  The root mean square velocity is inversely proportional to the temperature
•  The mean transitional kinetic energy of the molecules is proportional to the absolute temperature
Solution:
Q6. NH3 gas is liquefied more easily than N2. Hence
•  Van der Waals constants a and b of NH3 > that of N2
•  Van der Waals constant a andb of NH3 < that of N2
• a(NH3) > a(N2) but b(NH3) < b(N2)
•  a(NH3) < a(N2) but b(NH3) > b(N2)
Solution:
Q7.When the temperature is increased, surface tension of water
•  Increases
•  Decreases
•  Remains constant
•  Shows irregular behavior
Solution:
Q8.For a monoatomic gas kinetic energy =E. The relation with rms velocity is
•  u=(2E/m)1/2
•  u=(3E/2m)1/2
•  u=(E/2m)1/2
•  u=(E/3m)1/2
Solution:
Q9.Which of the following contains greatest number of N atoms?
•  22.4 L nitrogen gas at STP
•  500 mL of 2.00 M NH3
•  1.00 mol of NH4Cl
