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.
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.
No that is a physical property.
helium is a gas at room temperature.
Boiling helium is a physical change, not a chemical one. This process involves a change in the state of matter from liquid to gas due to the addition of heat, but it does not alter the chemical composition of helium itself. The helium atoms remain unchanged throughout this transition.
