Answer:
chemical change.
Explanation:
There are two types of changes in matter: physical change and chemical change.
physical change- it is a change in matter that alters only its physical properties or its physical appearance. This type of change is reversible. For example- freezing of water, the water turns into solid ice and it can be reversed by melting the ice.
chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.
From the process of respiration chemical energy in the form of ATP.
Answer:
1/4
Explanation:
The reason that the answer is 1/4 is because the young man, his grandfather, his father, and his mother equal 4 people. The young man is 1 person. 1 person/4 people = 1/4.
When an automotive battery is fully charged, the sulfuric
acid and water mixture will have a specific gravity of about 1.3. Specific
gravity is actually the difference in the weight of water in comparison to a specific
fluid. It is measured by a hydrometer. The amount of charge in the battery is
normally measured by the specific gravity of the battery. The specific gravity
of water is 1 and anything less than one is considered less dense while
anything that has a specific gravity of more than 1 is considered more dense
than water.
