Heated gases have lower kinetic energy and higher density.
Heated gases have lower kinetic energy and higher density.

Heated gases have higher kinetic energy and decreased density.
Heated gases have higher kinetic energy and decreased density.

Answer 1

The correct statement is:

Heated gases have higher kinetic energy and decreased density.

When gases are heated, their molecules move faster (higher kinetic energy), which causes them to spread apart. This increased motion leads to a decrease in density, causing the heated gas to rise in the container.
