Question

gas a and gas b have the same temperature. which has the higher gas pressure? gas a gas b neither; their gas pressures are the same

Explanation:

Step1: Recall gas - pressure principle

Pressure is due to gas - molecule collisions with container walls. More molecules mean more collisions.

Step2: Compare number of molecules

Gas A has fewer molecules than Gas B.

Step3: Determine pressure

Since temperature and volume are the same (implied as same - sized containers), more molecules lead to higher pressure. So Gas B has higher pressure.

Answer:

gas B
