Yes, boiling helium is a physical change. When helium transitions from a liquid to a gas upon heating, its chemical composition remains unchanged; only its state of matter alters. This process is reversible, as helium can be condensed back into a liquid by cooling.
No that is a physical property.
Temperature affects helium by changing its physical state. At higher temperatures, helium can transition from a liquid to a gas. Additionally, temperature can impact the behavior of helium gas, such as its diffusion rate or expansion properties.
