multiple - choice question which particles have a lower density? cold particles hot particles rewatch
Answer
Brief Explanations:
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 $\rho=\frac{m}{V}$ (where $\rho$ 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
