Question

A scientist heats a flexible container full of neon gas. What will most likely happen to the container as the gas absorbs heat? 

A. It will expand, because the neon atoms will move more quickly and get farther apart.


B. It will expand, because the neon atoms will get larger.


C. It will shrink, because the neon atoms will break apart into smaller pieces.


D. It will shrink, because the neon atoms will lose energy as heat, and move closer together.

Answer 1

A. It will expand because the neon atoms will move more quickly and get farther apart.

Answer 2

It will expand, because the neon atoms will move more quickly and get farther apart.

Step-by-step explanation:

When a gas is heated, its molecules absorb energy and move at higher velocities. When this happens, the gas molecules separate from each other and expand rapidly increasing the volume of the gas.

This increase in volume of the gas causes the container to expand also. Hence the answer.
