Why might a cup with a lid keep liquids hot or cold better than a cup without a lid?
The lid allows for more air circulation.
The lid makes the cup heavier, which traps more heat.
The lid changes the temperature of the air inside the cup.
The lid reduces heat exchange between the liquid and the air.
If you want to test the effect of adding hot water to different cups to see which one keeps water hot the longest, what is the independent variable?
The time of recording
The type of the cup
The amount of water
The starting temperature of the water
Why do we need to agree on a list of procedures before conducting an investigation?
To make sure all steps are followed consistently by everyone
So that each person can do the experiment differently
To make the experiment shorter
So that no instructions are the same
What pattern might you look for in temperature data when comparing tests with hot and cold water?
Differences in how quickly the temperature changes
Changes in the color of the water
Differences in the taste of the water
Changes in the volume of the water
When conducting a fair test with hot water in different cups, what should you ensure remains constant?
The time taken to pour the water
The color of the cups
The amount of water in each cup
The shape of the cups
Why does adding a lid help decrease the amount of water leaving the system?
A lid traps all the air inside the system.
A lid makes the system heavier.
The lid changes the chemical composition of the water
A lid prevents the water from escaping as vapor
If we could completely seal off the cup, do you think the temperature of the liquid inside would still change? Why?
No, because it would stay at the initial temperature forever.
No, because nothing can change in a sealed environment.
Yes, heat energy can still transfer to or from the cup’s surroundings.
Yes, because the water molecules would stop moving.
How does weighing each system at the start and end of the experiment provide insights into what happens to the water?
It helps determine if any mass is lost, indicating evaporation or condensation.
It ensures that the water was initially pure.
It confirms the temperature changes measured.
It verifies that the experiment was conducted properly.
What would happen to the temperature of hot water in a cup without a lid compared to a cup with a lid?
The cup without a lid would maintain its temperature.
The cup without a lid would cool down faster.
Both cups would cool down at the same rate.
The cup with a lid would cool down faster.
What is happening to the liquid water that can explain why the mass of the cup system decreases over time?
The water turns into gas and increases the mass of the system.
The water molecules evaporate, leaving the system and reducing mass.
The water molecules bond with air particles, doubling the mass.
The water solidifies and makes the cup heavier.
