00:00so chapter number 15
00:06molecular theory of gases came secure the relationship between temperature and average
00:12kinetic energy of particle in a case is this cancer option b temperature is directly proportional
00:20to average kinetic energy question number two standard condition of temperature and pressure
00:27stp referred to a gas at zero degree and one atmosphere if temperature is kept constant and
00:36volume of gas is double then pressure of a gas is this cancer will reduce to half
00:50or ever got no number in the number of molecule in to this cancer will be one mole of a
00:57substance
01:00mean translational kinetic energy per molecule of an ideal at zero degree
01:05so this will be 3 upon 2 kt any option a
01:14then normal body temperature 98.64 and at 37 degree centigrade
01:20then what pressure is going on
01:23so this is 1 upon 3 draw v square any option c
01:27in air at stp the average speed of the ms case number eight
01:43so this answer will be the option d
01:46i mean helium atom is greater than both oxygen and nitrogen
01:51then question 9 in the absolute temperature of gas is increased three times
02:02if gas is enclosed in an isolated container which is placed
02:08the temperature of the gas
02:09so the answer remains constant
