How does a sample of helium at 15 °c compare to a sample of helium at 215 k? the helium at 15 °c has a higher average kinetic energy than the sample at 215 k. the helium at 15 °c has lower nuclear energy than the sample at 215 k. the helium at 15 °c has slower-moving atoms than the sample at 215 k. the helium at 15 °c has smaller atoms than the sample at 215 k.

The correct answer is: 'The helium at 15 °C has a higher average kinetic energy than the sample at 215 K'.

Explanation:

Average kinetic energy of the helium atom at 15 °C .

Temperature of the gas = T = 15 °C = 288.15 K

Average kinetic energy is determined by formula:

Average kinetic energy of the helium atom at 215 K.

Temperature of the gas = T' = 215 K

Average kinetic energy is determined by formula:

The helium at 15 °C has a higher average kinetic energy than the sample at 215 K.Hence, it is the correct option.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'
