The mean speed of the molecules of a hydrogen sample equals the mean speed of the molecules of a helium sample. Calculate the ratio of the temperature of the hydrogen sample to the temperature of the helium sample.

The root mean square velocity of the molecules in a sample of helium is 5/7th that of the molecules in a sample of hydrogen. If the temperature of hydrogen sample is 0^(@)C , then the temperature of the helium sample is about

The root mean square velocity of the molecules in a sample of helium is 5//7th that of the molecules in a sample of hydrogen. If the temperature of hydrogen sample is 0^(@)C , then the temperature of the helium sample is about

The root mean square velocity of the molecules in a sample of helium is 5//7th that of the molecules in a sample of hydrogen. If the temperature of hydrogen sample is 0^(@)C , then the temperature of the helium sample is about

The root mean square velocity of the molecules in a sample of helium is (5/7)th that of the molecules in a sample of hydrogen.. If the temperature of the hydrogen sample is at 0^@C then the temperature of helium sample will be

At what temperature the mean speed of the molecules of hydrogen gas equals the speed from the earth?

At what temperature the mean speed of the molecules of hydrogen gas equals the escape speed from the earth?

At what temperature the mean speed of the molecules of hydrogen gas equals the escape speed from the earth?

All the molecules in a given sample of gas move with same speed.

All the molecules in a given sample of gas move with same speed.
