70 ml of water is poured into a beaker. 70 ml of another liquid is poured into the same beaker. The beaker is left undisturbed for some time. After some time, it is observed that the liquid forms a clear layer on top of water. If the density of water is 1 g/mL, what could be the density of the second liquid?

How does a sample of helium at 15 degree celsius compare to a sample of helium at 215 k? a) the helium at 15 degrees celsius has a higher average kinetic energy that the sample at 215 k. b) the helium at 15 degrees celsius has lower nuclear energy that the sample at 215 k. c) the helium at 15 degrees celsius has slower- moving atoms that the sample at 215 k. d) the helium at 15 degrees celsius has smaller atoms than the sample at 215 k.
