How does a sample of hydrogen at 10 degrees Celsius compare to a sample of hydrogen at 350K?
Sophie [7]

Answer:

We can compare the both sample by taking into account the kinetic energy.

By increasing the temperature kinetic energy of gas molecules increased.

Explanation:

It is known that kinetic energy of molecules is increased by increasing the temperature.

We are given with two sample of hydrogen one is at 10°C and other is at 350 K.

Hydrogen sample at 10°C = 273.15 + 10 = 283.15 k

Thus one sample is at 283.15 K and other is at 350 K. So, the sample at higher temperature i.e 350 K will have more kinetic energy of molecules.

While the sample at 283.15 K will have less speed of molecule and kinetic energy.
