When liquid nitrogen boils to form nitrogen gas, there are changes in the spacing of the particles and the overall density of the substance.
Which of the following correctly describes these changes?
The spacing between particles in nitrogen gas is larger than in liquid nitrogen, and the density of nitrogen gas is lower than liquid nitrogen.
The spacing between particles in nitrogen gas is larger than in liquid nitrogen, and the density of nitrogen gas is higher than liquid nitrogen.
The spacing between particles in nitrogen gas is smaller than in liquid nitrogen, and the density of nitrogen gas is lower than liquid nitrogen.
The spacing between particles in nitrogen gas is smaller than in liquid nitrogen, and the density of nitrogen gas is higher than liquid nitrogen.
