Why nitrogen diffuses faster in high temperature?

Description : Why nitrogen diffuses faster in high temperature?

Last Answer : Higher temperatures mean more heat energy which translates intomore kinetic energy of the molecules of nitrogen gas. This greaterkinetic energy allows the molecules to diffuse faster than at alower temperature and lower kinetic energy.

The closed circulatory system is more efficient. Since blood circulates only inside blood vessels it can do it with more pressure reaching farther distances between the organs where hematosis happens and the peripheral tissues. In addition the circulatory speed also heightens making possible more oxygen supply to great consuming tissues, like the muscle tissues that then can perform faster movements. Animals with an open circulatory system (with the exception of insects that do gas exchange independently from the circulation) are generally slower and have a low metabolic rate.

Description : Two passenger trains are running in the same direction on parallel tracks at 210km/hr and 150km/hr respectively. The faster train passes a man 81 sec faster than the slower train. Find the length of the faster train. A) 1250m B) 1150m C) 1350m D) 1450m

Last Answer : ANSWER: C  Explanation:  Speed of 1st train = 210km/hr  Speed of 2nd train = 150km/hr  Here the two passenger trains are running in same direction, so  Relative speed = (210 - 150)km/hr  = 60km ... faster train = relative speed * time taken by train to pass  = 50/3 * 81  = 1350m
