Question

sample a
temperature: 60°c
sample b
temperature: 45°c
which sample has the higher gas pressure?
sample a
sample b
neither, the samples have the same gas pressure

Explanation:

Step1: Recall gas - pressure and temperature relation

According to the ideal gas law (assuming volume and amount of gas are constant, $P = \frac{nR}{V}T$, where $P$ is pressure, $T$ is temperature, $n$ is the amount of gas, $R$ is the ideal - gas constant, and $V$ is volume), pressure is directly proportional to temperature.

Step2: Compare temperatures

Sample A has a temperature of $60^{\circ}C$ and sample B has a temperature of $45^{\circ}C$. Since $60^{\circ}C>45^{\circ}C$.

Answer:

Sample A
