Which statement best explains this result?(1 point) Responses Heated gases have higher kinetic energy and decreased density. Heated gases have higher kinetic energy and decreased density. Heated gases have higher kinetic energy and higher density. Heated gases have higher kinetic energy and higher density. Heated gases have lower kinetic energy and lower density. Heated gases have lower kinetic energy and lower density. Heated gases have lower kinetic energy and higher density.

Answer 1

The correct statement that best explains why a mixture of different gases rises to the top of its container when heated is: Heated gases have higher kinetic energy and decreased density.

When gases are heated, their kinetic energy increases, causing the gas molecules to move faster. This increased motion leads to an expansion of the gas, resulting in a decrease in its density. Since less dense gases rise above denser gases, the heated gas tends to rise to the top of its container.
