🔍 Key Concepts

• Vapor pressure as the tendency of a liquid to change into vapor • How temperature affects molecular motion in a liquid • The general relationship between temperature and pressure in a closed container of liquid and vapor

💭 Think About

• What happens to the motion of molecules in a liquid as temperature increases? How would that affect the number of molecules escaping into the vapor phase? • If more molecules enter the vapor phase above a liquid, what happens to the pressure those vapor molecules exert? • Which choice best describes a clear, consistent trend between temperature and vapor pressure, instead of being vague or contradictory?

✅ Before You Answer

• Make sure you connect increasing temperature with molecular motion/energy • Think about how vapor pressure at 0°C compares with vapor pressure at 50°C for the same liquid • Eliminate any options that claim no effect of temperature on vapor pressure or that contradict basic gas/liquid behavior
