Asyringe of volume 20 ml has just been used and now lies empty on the doctor's desk. the pressure in the office is 100,000 pa. assume that the air is an ideal gas consisting of nitrogen n2 (80%) and oxygen o2 (20%) molecules. k=1.38×10-23 j/k and the molar mass of oxygen is 32 g/mol. the syringe must be heated to high temperatures to sterilize it. when the syringe is at its maximum temperature, the number of oxygen molecules is 6.5 x 1019 (but the pressure, volume, and percent oxygen remain the same), what is the rms speed of the oxygen molecules?

for points guys

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
