which graph best represents the relationship between temperature and pressure? pressure temperature pressure temperature pressure temperature pressure temperature
Answer
Explanation:
Step1: Recall gas - law relationship
For a fixed amount of gas at constant volume, according to Gay - Lussac's law, $P = kT$ (where $P$ is pressure, $T$ is temperature in Kelvin, and $k$ is a constant). This is a direct - proportionality relationship.
Step2: Identify the graph type
A direct - proportionality relationship between two variables is represented by a straight - line graph with a positive slope passing through the origin (when $T = 0$, $P=0$ in the ideal case).
Answer:
The first graph (the one with a straight line having a positive slope)
