Annie goes to her local coffee place and buys a cup of coffee. The coffee is put in a cup with a lid that has a hole she has to punch out so she can take a drink. She rides to her workplace with the unperforated lid on the cup.

Which statements are true about this scenario?

Select TWO correct answers.

• This is a closed system.

• Energy cannot be exchanged between the environment and the system, but mass can be exchanged.

• Mass cannot be exchanged between the environment and the system, but energy can be exchanged.

• Energy is destroyed in this system.

• This is an open system.

Multiple Choice

The Law of Conservation of Energy states that energy is never __________________ or _________________, only transferred.

• created, destroyed

• created, subtracted

• added, subtracted

• destroyed, subtracted

Multiple Choice

Multiple Choice

This super powerful radiation can be used to treat cancer, and their bursts are studied by astronomers. They are sometimes used to treat cancerous tumors in the body by damaging the DNA of the tumor cells. However, great care must be taken, because these waves can also damage the DNA of surrounding healthy tissue cells.

• radio

• gamma

• visible light

• microwaves

• infrared

Multiple Choice

Energy from the sun arrives as electromagnetic radiation with a wide range of wavelengths and frequencies.

Which form of electromagnetic radiation has more energy than visible light waves have?

• Ultraviolet rays

• Radio waves

• Infrared Rays

• Microwaves

Multiple Choice

Why are X-ray images darker in regions where soft tissue is present?

• Soft tissue reflects X-rays completely.

• Soft tissue refracts X-rays back to the source.

• X-rays pass through soft tissue, leaving less impression on the film.

• Soft tissue absorbs all X-ray energy, making the image darker.
