Matter, Energy, and Change Quizziz

Which of the following examples is a type of kinetic energy?

• A stretched spring
• A bond between two atoms`
• The thermal energy of solid particles
• A weight hanging motionless on a string

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

Which of the following examples is a type of potential energy?

• A bouncing ball
• The chemical energy stored in fat molecules
• The thermal energy of hot gas particles
• Rain falling to the ground

Which of the following is an example of chemical energy?

• The temperature of a hot air balloon
• The speed at which electricity travels
• Gas particles bouncing off of each other
• The Calories of energy in a green apple

Which of the following is an example of thermal energy?

• The energy in a gallon of gasoline
• A wheel rolling down a hill
• Solid particles vibrating in place
• The bond between carbon atoms in a molecule

Which substance has the greatest average kinetic energy?

• Oxygen gas particles at 120 oC
• Water molecules at 50 oC
• Solid Iron pieces at 200 oC
• Ice cubes at -25 oC

If a rock heats up during the day, then cools down at night, what happens to the average kinetic energy of the particles in the rock?

• The kinetic energy remains the same.
• The kinetic energy increases, then decreases at night.
• The kinetic energy decreases during the day, then increases.
• Rocks have no kinetic energy

How much total kinetic energy can an explosion release ?

• The amount of chemical energy lost by the explosives.
• The total thermal energy of the explosives.
• It depends on the speed and height of the explosives.
• Explosions don’t release energy, but create new energy.

Which type of system may lose or gain energy but not lose or gain matter?

• Isolated system
• Closed system
• Open system
• Surrounding system

An isolated system could be used to prove which Law(s) ?

• The Law of Conservation of Mass
• The Law of Conservation of Energy
• Both the Law of Conservation of Mass and the Law of Conservation of Energy
• Neither Law would be true in an isolated system

Which of the following Energy transformations can violate the Law of Conservation of Energy ?

• Chemical energy to Heat Energy and Light Energy in a Forest Fire
• Chemical Energy to Kinetic Energy in our bodies’ metabolisms
• Light Energy to Chemical Energy in Photosynthesis
• All Energy Transformations should obey the Law of Conservation of Energy
