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.

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.
Their melting and boiling points of alkanes are relatively low. The higher the molecular weight (the greater the number of carbons), the higher the boiling point.
Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. ... Cold water is more dense and will sink in room-temperature water.
