Final answer:
The question pertains to calculating the change in volume of a helium gas sample using Charles's Law, which is a part of high school Chemistry focusing on gas behavior.
Step-by-step explanation:
The subject of this question is Chemistry, specifically relating to the behavior of gases. In the question, the student is given a scenario involving a volume of helium gas and its response to changes in temperature, assuming constant pressure. This scenario is typically analyzed using the Gas Laws, particularly Charles's Law, which relates the volume of a gas to its temperature when pressure is held constant.
Using Charles's Law, which states that V1/T1 = V2/T2 for a gas at constant pressure, students can solve for the unknown volume after a temperature change. For the given problem about helium, students would set up the equation with the initial volume and temperature, then solve for the final volume after the temperature increase.
Another example provided to help illustrate this concept is the expansion of a balloon. A balloon inflated with a certain number of breaths will have its volume increased proportionally to the number of additional breaths added, assuming all breaths are of equal volume and the temperature and pressure remain constant.
