Unit 5: Transfer of Info & Energy (I.6E, I.6F, I.6G)

Why do sound waves travel faster through liquids than through gases (like air)

• The particles in liquids are closer together than in air

• The particles in liquids are farther apart than in air

• The sound waves are magnified in liquids

• The sound waves are minimized in liquids

Renewable energy sources are globally equitable. This means...

• Renewable energy sources are implemented to all regions and countries around the world

• Renewable sources bring in a lot of money to all countries and regions globally

• Some countries and regions around the world have a lot more access to renewable energy sources than others

• All countries and regions around the world have access to a fair and proportionate share of renewable energy sources

The table shows the speed of waves through different mediums. Based on the table, all of the following are true statements except:

• Light can travel through a vacuum, but sound waves cannot

• Sound travels fastest through solids

• Light travels faster through all mediums compared to sound

• Light waves cannot travel through metals like steel

Which statement summarizes the chart?

• UV rays are more effectively blocked by lead and concrete than Gamma Rays

• All wave types travel through different types of mediums the same way

• Gamma Rays are more effectively blocked by Air and Glass than UV rays

• Both wave types are unable to travel through a vacuum

Which statement best explains why, as you walk through your home, your cell phone signal seems to grow stronger or weaker as you pass from room to room.

• Different rooms may contain different building materials that absorb or transmit cell signals differently

• The lighting in each room affects radio waves differently

• Your cell phone's battery is going bad

• If you move too quickly, you will lose signal

Why might countries choose to use natural gas despite it's serious environmental disadvantages?

• Natural gas is cleaner than other fossil fuels, energy-dense, and affordable.
• Natural gas produces more carbon emissions than oil.
• Natural gas is more expensive than coal.
• Natural gas is the only available energy source.
