Question

gases under pressure quick check. the ideal gas law is represented by pv = nrt. as volume is held constant and the temperature increases, how would the pressure be expected to change? (1 point). it would become zero. it would decrease. it would remain constant. it would increase.

Explanation:

Step1: Rearrange ideal gas law

Given $PV = nRT$. When $V$ (volume), $n$ (amount of gas) and $R$ (gas - constant) are constant, we can write $P=\frac{nR}{V}T$. Let $k = \frac{nR}{V}$, then $P = kT$.

Step2: Analyze relationship

Since $k>0$, $P$ is directly proportional to $T$. So when $T$ (temperature) increases, $P$ (pressure) will increase.

Answer:

It would increase.
