A chemical change occurs when the bonds between atoms and molecules change, and a new substance forms. This chemical change may or may not be permanent and may or may not physically affect an object. However, it always affects the chemical composition.

zavuch27 [327]

Answer:

It’s mass would be the same

Explanation:

Mass and weight are often used interchangeably in everyday conversation. For example, our medical records often show our weight in kilograms but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.

A light-year is a unit of a. time. c. mass. b. distance. d. density.

lana [24]

Answer: The correct answer is Option b. Distance.

Explanation:

Scientists and astronomers use this unit to measure the distance in space. A light year is a unit of distance and not time because light travels very fast and it travels a lot of distance in one year.

Light year is basically defined as how far the beam of light travels in a year.

Therefore, this light year is a unit of distance. Hence, the correct option is option b.

$1\text{ light year}=5.879\times 10^{12}miles$

Answer:

What inferences can you make about the melting points of the different substances and the motion of their particles, based on the data? (ignore that needed it here so i could see it better.)

Explanation:

Butter has a lower melting point than the cheese and the wax. The motion of the cheese were a little separated while the butter articles have more space in between. The wax had the closest particles.

I dont know if that makes sense?
