Heated gases have lower kinetic energy and lower density.

Heated gases have higher kinetic energy and higher density.
Heated gases have higher kinetic energy and higher 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 particles move more rapidly, which increases their kinetic energy. This increase in movement causes the gas to expand, leading to a decrease in density. As a result, the heated gas will rise above cooler, denser gases in a mixture.
