Question

Pls check someone thanks!

1. Which type of energy is most important when considering the heating and cooling of a building?(1 point)

A. thermal energy

B. chemical energy

C. electrical energy

D. potential energy

I chose A.

2. Which statement describes a design factor that should be included in an energy-efficient home built in cold climates?(1 point)

A. insulation that easily conducts thermal energy

B. windows that include multiple glass layers

C. light-colored roofing materials

D. trees that provide shade for the home

I chose A (again).

3. Why do many technological devices use metal?(1 point)

A. Metals allow for the flow of electrons.

B. Metals are an example of an insulator.

C. Metals limit the amount of charge flow.

D. Metals have low chemical reactivity.

I chose C, but I think It's A?

4. An environmental health scientist has studied the air quality in a small town. He has identified the types of chemicals that contribute to the bad air. An engineer reads an article the scientist wrote about the causes of this poor air quality. The engineer is interested in working with the scientist to improve air quality in this town.

What role could the engineer play to solve this problem? (1 point)

A. characterize the health effects of these chemicals.

B. draw a sketch of what the town looks like

C. design a bubbler used to trap the air particles

D. describe how long the chemicals stay in the air

I chose A.
check my answers please!

Answer 1

1. Correct, A. thermal energy is the most important for heating and cooling buildings.
2. Incorrect, the correct answer is B. Windows with multiple glass layers are a design factor that helps to insulate the home better in cold climates.
3. Incorrect, the correct answer is A. Metals allow for the flow of electrons, which is important in many technological devices.
4. Correct, the engineer could help design and implement solutions to improve the town's air quality based on the scientist's findings on the health effects and chemical properties of the contributing substances.

Answer 2

Alright, so for anyone in the future, here are the correct answers for: Physics and Chemistry in Design Quick Check in 8th grade:

1. Thermal energy
2. Windows that include multiple glass layers
3. Metals allow the flow of electrons
4. To confirm the best location on the roof to build the garden
5. Design a bubbler to used to trap the particles

Hope you all have an amazing day and God bless! He loves you!

Answer 3

It's great that you shared the correct answers, but just to clarify, the correct answer for question 4 is actually "To determine which areas in the town have the highest concentrations of the harmful chemicals." And there is no question 5 in the original post. Thank you for trying to help and have a great day!
