Answer:
lightning candel is not a physical change.
when you light the candel the wax gets melted which cannot be reversed.
as physical change is that change in which no new substances are formed abd is reversible.
In the option above shattering the plate doesnot make any chemical change likewise cutting hair also doesnot mean so, and boiling water can be condensed.

Answer:
The answer is
<h2>15.86 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of glycerol = 20 g
density = 1.261 g/mL
The volume is
We have the final answer as
15.86 mL
Hope this helps you
Your answer is D. Since there is little to no magnetic field to wire, if it is copper which most wires are, there will be no voltage in a wire.
To determine the mass of the sample, first find the volume difference after and before the aluminum was placed, the volume change is equal to the volume of the submerged object, in this case aluminum.
Then knowing volume of aluminum and the density of it, we can solve for the mass.
D = m/v
Dv = m
2.7 g/ml • 8 ml = 21.6 grams.
