What is the mass of an aluminum cylinder that has a volume of 1.50m3

Answers

Answer: The mass of aluminium cylinder is 4065 kg.

Explanation:

Density is defined as the ratio of mass of the object and volume of the object.

Mathematically,

$\text{Density}=\frac{\text{Mass of the object}}{\text{Volume of the object}}$

We are given:

Density of aluminium = $2710kg/m^3$

Volume of aluminium cylinder = $1.50m^3$

Putting values in above equation, we get:

$2710kg/m^3=\frac{\text{Mass of aluminium cylinder}}{1.50m^3}\n\n\text{Mass of aluminium cylinder}=4065kg$

Hence, the mass of aluminium cylinder is 4065 kg.

Aluminium density: 2700g/m^3

therefore; 2700g/m^3 X 1.50m^3 = 4050g = 4.05Kg

Just use the units of density (mass/volume) and the units of what's given to figure it out :)

When the pressure exerted on a confined gas at constant temperature is doubled, the volume of the gas is

Answers

When the pressure exerted on a confined gas at a constant temperature is doubled, the volume of the gas is halved. I answer to your question is 'halved'. I hope this helps you on your assignment.

Answer: When the pressure exerted on a confined gas at constant temperature is doubled, the volume of the gas is halved.

Explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$

where,

$P_1$ = initial pressure of gas = p

$V_1$ = initial volume of gas = v

$P_2$ = final pressure of gas= 2p

$V_2$ = final volume of gas = ?

Putting values in above equation, we get:

$p* v=2p* V_2$

$V_2=(v)/(2)$

Thus the final volume of the gas is half of the initial volume.

In which part of the Milky Way galaxy is our sun located?halo
bulge
center
spiral

Answers

The Sun's location in the Milky Way, specifically in the Orion Arm, about 26,000 light years from the center.

Our Sun is located in the spiral part of the Milky Way galaxy. More specifically, it is found in one of the galaxy's spiral arms, known as the Orion Arm, or sometimes the Orion Spur.

The Milky Way consists of several components: the halo, bulge, disk, and spiral arms. The center, or bulge, contains older stars and a supermassive black hole. The halo contains globular clusters, while the disk contains stars of various ages, gas, dust, and the spiral arms, which have a higher density of gas and dust.

In contrast, our Sun is located about 26,000 light years from the center in the disk, residing in one of the spiral arms where star formation is quite active.

The pH scale for acids and bases ranges from _____.A.) 1-7
B.) 0-14
C.) 1-14
D.) 1-12

Answers

The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14. From here we can derive the values of each concentration.

-log[H+ ] + -log[OH- ] = -log[10-14]

pH + pOH = 14

So pH = 14 – pOH and pOH = 14 – pH

the correct answer is B.) 0-14

Which of the following is considered to be a dangerous procedure in the laboratory setting? a. Pouring all liquids, especially acids and bases, over the sink
b. Wearing goggles
c. Pushing glass tubing, thermometers, or glass thistle tubes through a rubber cork
d. Pointing the mouth of a test tube that is being heated away from you and others
e. Knowing where the fire extinguisher and eyewash stations are located

Answers

The answer is (A) , because all other options are safety precautions, not dangerous.

I think it's c because a is good as it won't cause spills on the floor, b you must do for eye safety d) is also for safety so chemicals don't burn or spit at you And e is needed incase a fire occurs or something is in your eye and immediately needs washing out therefore c is the only one which could be a danger
