colored ball represents one gas particle. sample a temperature: 150°c sample b temperature: 150°c which sample has the higher gas pressure? sample a sample b neither; the samples have the same gas pressure

colored ball represents one gas particle. sample a temperature: 150°c sample b temperature: 150°c which sample has the higher gas pressure? sample a sample b neither; the samples have the same gas pressure

Answer

Explanation:

Step1: Recall ideal gas law

$PV = nRT$. At constant volume ($V$) and temperature ($T$), pressure ($P$) is proportional to the number of moles ($n$). More particles mean more moles.

Step2: Count gas particles

Sample A has 6 gas particles, Sample B has 7 gas particles.

Step3: Determine pressure

Since Sample B has more particles, it has higher $n$. So Sample B has higher pressure.

Answer:

Sample B
