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 is the third option. Adding heat to a gas increases its kinetic energy. Causing it to move faster and farther.

Answer 2

temperature is directly proportional to the kinetic energy of an ideal gas.

Answer 3

are there any doubts?

Answer 4

you were right thanks a bunch!
