Considering the value of ideal gas constant in S. I. unit, find the volume of 35g O2 at 27℃ and 72 cm Hg pressure. Later, if we keep this pressure constant, the r. m.s velocity of this oxygen molecules become double at a certain temperature. Calculate the value of this temperature.

radiation

explanation:

heat is transmitted by radiation

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
