In interstellar space it is estimated that atomic hydrogen exists at a concentration of one particle per cubic meter. if the collision diameter is 2.5 x 10 m, calculate the collision frequency and the mean free path. the temperature of interstellar space is 2.7 k. crno am of ch weighing 175

Ametal with a large number of free flowing electrons most likely has good conductivity

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
