Question

use the following information to answer the next question. the graph below illustrates the relationship between the pressure and absolute temperature of an ideal gas kept at a constant volume: graph with pressure on x - axis and temperature in k on y - axis. 4. the graph above best illustrates which gas law? charles law gay - lussac law avogadros law boyles law

Explanation:

Step1: Recall gas - laws

Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its temperature (in Kelvin), $V\propto T$. Gay - Lussac's Law states that at constant volume, the pressure of a gas is directly proportional to its temperature, $P\propto T$. Avogadro's Law relates the volume of a gas to the number of moles at constant temperature and pressure. Boyle's Law states that at constant temperature, the pressure and volume of a gas are inversely proportional, $P\propto\frac{1}{V}$.

Step2: Analyze the graph

The graph shows a direct relationship between pressure ($P$) and temperature ($T$) at a constant volume (since the problem states "at a constant volume"). This is in accordance with Gay - Lussac's Law.

Answer:

Gay - Lussac's Law
