How does a sample of hydrogen at 10 °c compare to a sample of hydrogen at 350 k? the hydrogen at 10 °c has a higher average kinetic energy than the sample at 350 k. the hydrogen at 10 °c has lower nuclear energy than the sample at 350 k. the hydrogen at 10 °c has slower-moving molecules than the sample at 350 k. the hydrogen at 10 °c has smaller molecules than the sample at 350 k. i really suck at chem, this is my second time taking the class and i still don't understand.. someone me pls

The hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Explanation: -

Temperature of the hydrogen gas first sample = 10 °C.

Temperature in kelvin scale of the first sample = 10 + 273 = 283 K

For the second sample, the temperature is 350 K.

Thus we see the second sample of the hydrogen gas more temperature than the first sample.

We know from the kinetic theory of gases that

The kinetic energy of gas molecules increases with the increase in temperature of the gas. The speed of the movement of gas molecules also increase with the increase in kinetic energy.

So higher the temperature of a gas, more is the kinetic energy and more is the movement speed of the gas molecules.

Thus the hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.
