Answer 1

The 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 molecules to move faster and spread apart. This increased movement results in a decrease in density, making the heated gases less dense than the cooler air around them, allowing them to rise.
