HMS T.E. Chapter 2 Study Guide

Daniel and Mason each have a cup of water at different temperatures. If they mix their water together, when would the water stop changing temperature?

• When both samples were the same temperature

• When Mason's water is colder than Daniel's

• When Daniel's water is colder than Mason's

Anika has a hot cup of coffee (Sample A) and Zoe has a cold glass of water (Sample B). If they were to mix their drinks, what would happen to the speed of the molecules in each drink?

• Anika's coffee molecules would start to move faster and Zoe's water molecules would move slower

• Anika's coffee molecules would start to move slower and Zoe's water molecules would move faster

• Both Anika's coffee and Zoe's water molecules would move faster

• Neither drink's molecules would change speed

Ethan takes a bite of hot broccoli and burns the roof of his mouth. What is happening to the molecules in his mouth when this happened and what is happening to the molecules of broccoli that burned him?

• The molecules in his mouth speed up and the molecules of broccoli slow down

• The molecules in his mouth slow down and the molecules of broccoli speed up

• The molecules in his mouth explode because they are so hot

• The molecules in his mouth speed up but nothing happens to the molecules of broccoli

Rank these samples from the one with the least kinetic energy to the one with the most kinetic energy

• A, B, C
• B, C, A
• B, A, C
• They all have the same kinetic energy

Jessie has a fever and used a cool wash cloth to get relief. Which of the statements best describes what happened?

• As the faster-moving molecules of his hot forehead move, they bump into the slower-moving molecules of the cold washcloth, transferring kinetic energy from your forehead to the washcloth and reducing Jessie's fever.
• As the slower moving molecules of his forehead move, they bump into the faster-moving molecules of the washcloth, transferring kinetic energy from the washcloth to his forehead.

Ava has a hot cup of coffee (Sample A) and Oliver has a cold soda (Sample B). If they were to mix their drinks, what would happen to the speed of the molecules in each drink?

• Sample A would move slower and sample B would move faster

• Sample A would mover faster and sample B would move slower

• Sample A would move slower, but sample B would not change

• Neither sample's molecules would change speed
