Explanation:
You will need an empty bottle (with a medium or small opening) made of clear glass, some hot water, and an ice cube.
Place some hot water in the bottom of the bottle and put the ice cube over the opening of the bottle so that it rests on top and drips into the bottle.
B. Physical change; physical property of flammability
C. Chemical change; chemical property of reactivity
D. Chemical change; chemical property of flammability
Answer:
C = chemical change, chemical property of reactivity.
Explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
The reaction of iron with air in the presence of water lead to the production if ion oxide which is called rusting. It is a chemical change.
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
Physical Change:
The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.
These changes were reversible.
They have same chemical property.
These changes can be observed with naked eye.
Example
Water converting to Ice
Water converting to gas
In this water molecule remain the same only they rearrange themselves that change its state of mater not composition
Answer:
C) Chemical Change; Chemical Property of reactivity
Explanation:
I took the test
Answer:
The body could produce too many cells and if too many are clustered together, cell communication, signaling, and transport of materials could be limited or even stopped entirely. Another reason is becuase the more cells andd individual has, the more risk for developing cancerous or mutated/harmful cells.
to bring oxygen into the lung
B.
to put carbon dioxide into all blood vessels
C.
to expel waste products from the body
D.
to transport materials throughout the body
D
oh yeah oh yeah oh yeah
B) conduct a single trial and make sure the experiment can be replicated
C) conduct repeated trials and make sure the experiment cannot be replicated
D) conduct a single trial and make sure the experiment cannot be replicated
Answer;
A) conduct repeated trials and make sure the experiment can be replicated.
Explanation;
Scientific experiments are conducted to figure out answer and solve a problem and get info about hypothesis.
-Scientific methods involvesobservation, developing questions, formulating hypothesis, making an experiment, collecting data and analyzing results, making a conclusion, and communicating results.
Answer:
A.
