Question

I'll give you a medal :)

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

It will shrink because the helium atoms will break apart into smaller pieces.

It will expand because the helium atoms will get larger.

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

It will shrink because the helium atoms will lose energy as heat and move closer together.

Answer 1

It will expand because the helium atoms will move more quickly and get farther apart. This is your answer because as the particles get more heated, they start to increase the kinetic energy and move more.

Answer 2

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

Step-by-step explanation:

When a gas absorbs heat, the internal energy of its molecules increases, the gas intend to expand because, with more energy, the molecules will move quickly and will get farther apart.

If the container is not flexible, it will contain the molecules, and the gas pressure will increase, but if it's flexible, it will permit the gas to expand and will expand too.
