Question

Five samples of neon gas are described in the table below. Rank the samples in order of increasing average kinetic energy of the atoms in them. That is, select "1" next to the sample in which the neon atoms have the lowest average kinetic energy. Select "2" next to the sample in which the neon atoms have the next lowest average kinetic energy, and so on. sample average kinetic energy of atoms in sample amount pressure temperature -28 °C 1.2 mol 2.0 atm Choose one) 1.7 mol 1.2 am -61. °C Choose one) 1.5 mol 3.0 atm (Choose one) 13 mol -46. °C (Choose one) 2.0 mol 15 atm - 35 °C (Choose one)
