Why does adding a lid help decrease the amount of water leaving a system?

• A lid traps all the air inside the system.

• A lid changes the chemical composition of the water.

• A lid prevents water molecules from escaping as vapor.

• A lid makes the system heavier.

If a cup is completely sealed, will the liquid's temperature still change?

• No, it will remain at the initial temperature.

• Yes, heat energy can still transfer.

• Yes, water molecules will stop moving.

• No, nothing can change in a sealed environment.

What is happening to the liquid water that explains a decrease in the cup system's mass over time?

• Water turns into gas, increasing mass.

• Water molecules evaporate, reducing mass.

• Water molecules bond with air, doubling mass.

• Water solidifies, increasing weight.

Why does adding a lid help decrease the amount that the water temperature changes?

• It introduces cold or hot air.

• It increases water evaporation.

• It insulates the system, keeping heat in.

• It changes the water's chemical composition.

What is the effect of a lid on the rate of evaporation?

• Increases the rate.

• Allows more air circulation, increasing rate.

• Has no effect.

• Reduces the rate by trapping steam.

How would you determine the impact of mass loss on water temperature change?

• By observing color change.

• By measuring volume before and after.

• By checking the time for cooling down.

• By measuring initial and final mass and temperature.
