Observe the activity in your classroom. You can observe people, objects, and parts of your actual classroom as you begin to notice changes in matter. Collect data for two examples of changes in matter. Use the Changes in Matter observation questions to determine if your examples are physical or chemical changes. Your answer should include the following: two examples, the type of change for each, and how the examples were formed. You can use this format:

Example 1:

Type of Change:

How examples were formed:

the answer is

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

i do not get it   at all

the answer is yes

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
