2023 6.2 Practice Test 1

Jevin conducted a warm coffee test at their local cafe. Which choice provides the best conclusion about how lids affect the temperature of the coffee inside a cup?

• In conclusion, all the coffee temperatures decreased.

• In conclusion, not having a lid on the coffee cup at the cafe will keep your drink warm because the data shows that the temperatures are hotter than when there is a lid.

• In conclusion, having lids was better at keeping coffee warm compared to not having a lid because the data shows less temperature change with a lid.

2. Lily left a glass of water in the sun. What happens to the water in the glass during the process of evaporation?

• Molecules of water vapor in the glass stick together to become a droplet.

• Molecules of water in the glass escape the liquid to become a gas.

• Molecules of water in the glass become solid ice.

3. Sophia is having a picnic on a hot summer day. She notices water droplets appearing on the outside of her cold soda cans. Where are these droplets coming from?

• Seeping through the can wall

• Melting from the ice inside the can

• Condensing from the surrounding air

4. Abigail, Elijah, and James are observing a cold glass of water on a hot day. What happens when CONDENSATION occurs on the outside of the glass?

• Molecules of water vapor in the air stick together on the cold surface of the glass to form a droplet.

• Molecules of water inside the glass escape to become a gas.

• Molecules of water inside the glass freeze to become solid ice.

5. Abigail, Isla, and Emma conducted an experiment. They poured hot coffee into two travel mugs. One mug had a lid and the other didn't. They measured the weight of the mugs at the start and after 10 minutes. What does this data prove about lids?

• Lids prevent matter from leaving a cup system

• Lids weigh 0 grams

• Lids maintain the temperature at zero degrees in a cup system

6. During a science experiment, Anika, Charlotte, and Priya observed the droplets that formed on their cold water glasses. They put lids on the glasses and weighed a cold glass of water at 0 minutes and at 10 minutes. Why is the mass of the glass increasing?

• Water is seeping through the glass walls.

• Water is escaping the lid, making it have more mass.

• Water from the air is sticking to the glass, making it have more mass.

Kai, Isla, and Aria conducted an experiment in which they recorded a video and collected data on a cup's mass over time. Based on the video and data table, explain what is happening to the cup's mass over time.

• The mass is decreasing.

• The mass is increasing.

• The mass is staying the same.

8. Maya observed a glass of water left outside in the sun. Based on her observations and the data she collected, can you explain why the mass of the glass of water decreases over time?

• The water in the glass is freezing.

• The water in the glass is transmitting.

• The water in the glass is evaporating.

• The water in the glass is condensing.

• A

• B

• C

Emma, Mia, and Priya are conducting an experiment in their science class. They are asked to create a model that represents a gas. Which of the following models created by them correctly shows a particle model for a gas?

• A

• B

• C
