Question

Interstellar dust particles help cool the nebular cloud by _____.

slowing particles down
allowing particles to collect
clumping particles together
attracting the heat of the nebular cloud

Answer 1

Answer: Attracting the heat of the nebular cloud

Heat is lessened by interstellar dust through attraction of heat in the gas cloud. The nebular cloud’s heat, coming from radiation emitted by stars, is indirectly cooled down by dust through ionization and beams it towards space.
