Module 2 Quiz

Which statement accurately describes what happens when water turns to ice in terms of energy?

• The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to solid.
• The water releases energy which causes chemical bonds to form, changing water into ice.
• The water absorbs energy which causes chemical bonds to form, changing water into ice.
• The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a solid.

In the first law of thermodynamics, Change in E = Q-W, what does change in E  stand for?

• the heat added to the system
• the change in the internal energy of the system
• the work done by the piston
• the internal energy of the system

The first law of thermodynamics states that Change in E = Q-W  . How is this also a statement of the principle of conservation of energy?

• The energy that flows into the system is transformed into heat and work.
• The heat that flows into the system is transformed into work and a change in internal energy.
• A change in internal energy causes work to be done and heat to flow into the system.
• The work that is done by the piston is transformed into heat and a change in internal energy.

What is the part of the steam engine that does the work?

• the cylinder
• the flywheel
• the turbine
• the piston

Which activity involves using fossil fuels directly or indirectly?

• cooking hot dogs on a campfire
• using crayons to color
• eating fresh fruit for snack
• walking to school

How much ancient plant debris is necessary to form one foot of coal?

• one foot of plant debris
• ten feet of plant debris
• fifty feet of plant debris
• one hundred feet of plant debris

What is the main difference between an internal combustion engine and an external combustion engine?

• An internal combustion engine doesn't have a cylinder and a piston.
• The burning of fuel occurs inside the cylinder with the piston in an external combustion engine.
• The burning of fuel occurs inside the cylinder with the piston in an internal combustion engine.
• An external combustion engine doesn't have a cylinder and a piston.

Which ones are all renewable resources?

• coal, biomass, solar
• hydroelectric, natural gas, solar
• coal, natural gas, oil
• hydroelectric, biomass, solar

Massive amounts of destructive energy are released when a nuclear fission bomb explodes. Where does that energy come from?

• A chain reaction occurs when uranium atoms split, releasing nuclear energy.
• Molecules break down, releasing chemical energy.
• Molecules are created, releasing chemical energy.
• Hydrogen atoms fuse together into helium, releasing nuclear energy.

Where does fusion regularly occur and what kind of energy is produced?

• Fusion occurs in a nuclear power plant. The energy produced is electricity and light.
• Fusion occurs inside the Earth. It heats magma, which can then be used to heat homes or generate electricity.
• Fusion occurs inside the sun. It creates the light and heat that sustain life on Earth.
• When wood burns, fusion occurs. The energy produced is light and heat.
