I need answer ASAP PLZ! First one to answer will get a brainliest!!

Divers found two substances on the bottom of the ocean. At room temperature, both substances are liquid. Scientists then transferred the same amount of energy out of both substances. When a scientist checked again, Substance 1 had changed phase, but Substance 2 had not. How are Substances 1 and 2 different?

Which of these actions requires KINETIC Energy? Choose all of the correct answers.

- Sleeping
- Swimming
- Turning a doorknob
- Listening to music
- Hitting a tennis ball
- Waiting at a red light

Does a tree falling over in a forest make a sound if there is no receptor (human or animal ear) to hear it? In your answer, describe why you think it does or does not. Describe how you would test your hypothesis. Use relevant terms.

A group of students is tasked with developing a checklist for determining whether a material undergoes a chemical or physical change. The students make a preliminary list of properties that they can test and classify each as either a chemical or physical property.

Chemical Property Physical Property
bubbles when treated with acid color
burns when placed in a candle flame odor
density hardness
boiling point mass
dissolves in water melting point
Several other students in the class claim that the checklist is incorrect.

What change should the group make to the checklist to correct their mistake?


Boiling point and density should be moved to the physical property side of the list, and color and odor should be moved to the chemical property side of the list.


Boiling point and density should be moved to the physical property side of the list, and hardness and mass should be moved to the chemical property side of the list.

Dissolves in water and boiling point should be moved to the physical property side of the list, and odor and mass should be moved to the chemical property side of the list.

Density and boiling point should be moved to the physical property side of the list.

Draw a diagram that shows how Mark and Gina can model the positions of the Sun, Earth, and the Moon, and their orbital paths, during a solar eclipse. You must use all of the tools in your design: lamp, tennis ball, golf ball, and yarn.

if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??

Which observation indicates a chemical property?


slowly dissolves


turns cloudy


turns black


gritty

Data just came in about the space pod's mission and the thrusters fired for exactly the same about of time and at the same force as they have in past missions. Nothing about the pod's thruster force was different. Based on this new evidence, neither of our previous claims could be true!


We are left with the same question: why didn't the pod dock like it was supposed to do?

(B) Begin moving in anticipation of where the ball will land
(C)Stay in ready position and move only when the ball lands
(D)Stay in ready position and wait to see if it bounces off a side wall
