Which of the following best describes thermal energy?
The total energy of all the particles in a substance
The energy needed to move an object
The energy stored in food
The energy from the sun
Which organ is responsible for most nutrient absorption in the digestive system?

What happens to the particles of a substance when it is heated?
They slow down
They move faster
They disappear
They become smaller
Which of the following best describes the difference between heat and temperature?
Heat is a measure of how hot something is; temperature is the total energy of particles.
Heat is energy transferred between objects; temperature is a measure of how hot or cold something is.
Heat and temperature are the same thing.
Temperature is energy in motion; heat is stored energy.
Which cell structure is known as the "powerhouse" of the cell?
Nucleus
Mitochondria
Ribosome
Cell wall
Compare the arrangement of particles in a solid, liquid, and gas.
Solids have closely packed particles, liquids have loosely packed particles, and gases have particles far apart.
Solids and liquids have particles far apart, gases have closely packed particles.
All states have the same particle arrangement.
Gases and solids have loosely packed particles, liquids have closely packed particles.
If you place an ice cube in a warm room, which phase change will occur and why?
Freezing, because the ice cube loses energy
Melting, because the ice cube gains energy from the surroundings
Condensation, because water vapor forms
Sublimation, because the ice turns directly into gas
Which phase change occurs when water vapor turns into liquid water, and what is this process called?
Freezing
Condensation
Melting
Sublimation
A student observes that when a cold can of soda is left out on a warm day, water droplets form on the outside of the can. Explain why this happens.
The soda is leaking
Water vapor in the air cools and condenses on the cold can
The can is melting
The soda is evaporating
You are given three samples: ice, liquid water, and steam. Predict which sample has the highest thermal energy and explain why.
Ice, because it is the coldest
Liquid water, because it is in the middle state
Steam, because its particles move fastest and are farthest apart
All have the same thermal energy
Compare a plant cell and an animal cell. Which feature is only found in plant cells?
nucleus
mitochondria
cell wall
cytoplasm
A student eats a sandwich. Describe the path the food takes through at least two human body systems and how they work together.
It goes straight to the brain and helps with thinking.
The food is broken down by the circulatory system and stored in the lungs.
The digestive system breaks down the food, and the nutrients are absorbed and carried by the circulatory system.
The skeletal and muscular systems digest the food.
