Final answer:
Temperature affects the volume of a flexible gas-filled container because volume is directly proportional to temperature, as stated by Charles' Law. So, with higher temperature, volume increases.
Step-by-step explanation:
How temperature affects the volume of a flexible gas-filled container is an important concept in Physics, specifically in the study of thermodynamics and gas laws. According to Charles' Law, at constant pressure and amount of gas, the volume of a gas is directly proportional to its temperature. This means that if you increase the temperature of a gas in a flexible container, which allows for expansion, the volume of the gas will also increase.
When temperature is raised, the kinetic energy of the gas particles increases, causing them to move more rapidly and collide with greater force against the container walls. In a flexible container, this increased force will cause the container to expand, thereby increasing the volume. Conversely, when the temperature decreases, the particles lose kinetic energy, move less, and exert less force on the container walls, which results in a decrease in volume.
Therefore, the correct answer to the student's question is:
A) Volume increases with higher temperature.
