Density is measured in units of mass per units of volume. It can be thought of as a unit rate. The mass of a block of aluminum is 9.45 grams. The volume is 3.5 cubic centimeters (cm³).
What is the density of aluminum?
Answer:
you answer will be 2.7
Step-by-step explanation:
you just have to divide the 9.45 to 3.5 and you got your answer
The density of the aluminum will be 2700 kilograms per cubic meter.
What is the density?The number of molecules per unit volume is known as density. The SI unit of the density is kilograms per meter cube. The density is a scalar quantity. More density means more the number of molecules present in a unit volume. Then the density is given as,
Density = Mass / Volume
A chunk of metal weighs 9.45 grams. 3.5 cubic centimeters is the volume.
Then the density of the aluminum is given as,
D = 9.45 / 3.5
D = 2.7 grams per cubic cm
D = 2700 kilograms per cubic meter
The density of the aluminum will be 2700 kilograms per cubic meter.

What is arithmetic progression?A series in which the differences between each pair of following words are the same is known as an arithmetic progression.An arithmetic progression is a series in which every phrase—aside from the initial term—is created by multiplying the preceding term by a predetermined amount.given:
12, 13, 14, ......111.
first term, a= 12
d= 13-12= 1
[tex]a_n[/tex] = 11
Now,
[tex]a_n = a+ (n-1)d\\[/tex]
111 = 12 + (n-1) 1
111-12= n-1
n-1 = 99
n= 100
Hence, there are are 100 Natural Terms present there.

What are the two things that happen to water molecules when heat energy is added to air?
Answer:
The more thermal energy added, the greater the attraction between molecules. The molecules gain kinetic energy, move farther apart, and become a gas. The water molecules become packed closer together, and their temperature increases. Each water molecule gives up kinetic energy and eventually stops moving.
