Question

Complete the CER by writing a paragraph to explain your reasoning.Take a look at the image. The three beakers represent the same gas in the same liquid, but each has a different temperature set on the hot plate. Question: What is the relationship of temperature to pressure in a gas?1pt Claim: A one-sentence answer                                                                                                                                                                                                                       1pt Evidence Provide data to support your claim.Do not explain your evidence 2pts ReasoningExplain why or how your evidence supports your claim.Include an explanation of the kinetic molecular theory.Include an explanation of the correct gas law.

Answer 1

Claim: As the temperature of a gas increases, the pressure of the gas also increases when the volume is held constant.

Evidence: In the experiment, when the temperature was set higher in the beakers, the recorded pressure of the gas was higher compared to the beakers set at lower temperatures.

Reasoning: This evidence supports the claim because of the kinetic molecular theory, which states that gas particles are in constant motion and that their kinetic energy increases as temperature rises. As the temperature increases, the particles move more rapidly, leading to more frequent and forceful collisions with the walls of the container, thereby increasing pressure. This relationship is described by Gay-Lussac's law, which indicates that the pressure of a gas is directly proportional to its absolute temperature when the volume is held constant. Therefore, the observed increase in pressure with temperature aligns perfectly with the predictions made by both the kinetic molecular theory and gas laws.
