The law of conservation of mass states that <u>matter cannot be created or destroyed.</u>
<u />
The law of conservation of mass states that the mass of the reactant must be equal to the mass of the product.
In 18th century law of conservation of mass was given by Levoisier.
It states that mass is neither created nor destroyed.
Example -
- when wood burns the mass of the suit ,ashes and gases equal to the original mass of the charcoal.
- after heating the ice it will convert into water. Mass of the ice does not change after undergoes a physical. Change.
The law of conservation of mass states that <u>matter cannot be created or destroyed.</u>

Two things are needed to complerely describe a force: its strength and its direction. An arrow indicates both.
Answer:
The brightness of each bulb would remain the same even though the total resistance of the circuit would decrease.
Explanation:
Brightness of the bulb is given as
since all bulbs are connected in parallel so here voltage across each bulb will remain same and resistance of each bulb is "R"
So here power across each bulb will remain the same always.
So there will be no effect on the power or brightness of bulb.
Now we also know that equivalent resistance is given as
so here equivalent resistance will decrease on adding more resistance in parallel.
so correct answer will be
The brightness of each bulb would remain the same even though the total resistance of the circuit would decrease.
Answer:
False
Explanation:
The density is mass divided by volume
D.
This is an accordance with Newton's First Law of Motion, stating that objects in motion remain in motion and objects at rest remain at rest unless acted upon by an external force.
