A certain gas is taken to the five states representes by dots in the graph. The plotted lines are isotherms. Order of the most probable speed `v_(p)` of the molecules at these five states is

Nitrogen is in equilibrium state at T=421K .The value of most probable speed, v_(mp) is

The root mean square velocity, V_(rms) ,the average velocity v_(av) and the most probable velocity, v_(mp) of the molecules of the gas are in the order

The root mean square velocity, V_(ms ,the average velocity v_(av) and the most probable velocityv_mp of the molecules of the gas are in the order

Five molecules of a gas have speed 2, 4, 6, 8 km//s . Calculate average speed. Rms speed and most probable speed of these molecules.

A sample of ideal gas is taken through the cyclic process shown in the figure. The temerauture of the gas in state A is T_(A) =200 K. In states B and C the temperature of the gas is the same. Which of the following graphs best reprsent the cyclic process in T-V diagram

Suppose a container is evacuated to leave just one molecule of a gas in it. Let v_(mp) and v_(av) represent the most probable speed and the average speed of the gas, then

Let barv,v_(rms) and v_p respectively denote the mean speed. Root mean square speed, and most probable speed of the molecules in an ideal monatomic gas at absolute temperature T. The mass of a molecule is m. Then

An object whose density is Pob falls from a certain height into a liquid whose density is pliq In the figure the potential energy W of the object is plotted along the vertical axis and the position of the object (its altitude) is plotted along the horizontal axis. The potential energy of the object at the level of the liquid is taken zero and the positive direction of the vertical axis (the W axis) is the one pointing upward from the liquid's surface. Determine which of the five straight lines, 1-5 , corresponds to an object with the highest density and which to an object with the lowest density. Is there a straight line among these five for which Pob = (112) Pliq ? The arrows on the straight lines point in the direction of motion of the object.
