Question

multiple - choice question which particles have a lower density? cold particles hot particles rewatch

Explanation:

When particles are heated, they gain kinetic energy and spread out, increasing the volume they occupy while the mass remains the same. Using the density formula $
ho=\frac{m}{V}$ (where $
ho$ is density, $m$ is mass, and $V$ is volume), an increase in volume leads to a decrease in density. So hot particles have lower density.

Answer:

hot particles
