A balloon is filled with helium gas. What will happen as the average kinetic energy of the helium particles increases?The balloon will decrease in total volume.
The temperature of the balloon will decrease.
The gas atoms will strike the sides of the balloon more often.
The gas inside the balloon will change into a liquid.

Answers

Answer 1

Answer:

Answer: The gas atoms will strike the sides of the balloon more often.

Explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

$K=(3RT)/(2)$

K= kinetic energy

R= gas constant

T= temperature

From above, it is visible that kinetic energy is directly related to the temperature of the system.

So if average kinetic energy of the system increases , the speed of the molecules will be more and hence the gas atoms will strike the sides of the balloon more often.

Answer 2

Answer: C). As particles gain kinetic energy, they will speed up. With this new velocity they will collide with the sides of the wall more frequently by nature.

How many atoms of carbon are in 24 grams of carbon?a) 1.2 x 10²⁴ atoms
b) 1.7 x 10²⁶ atoms
c) 1.2 x 10²⁵ atoms
d) 3.0 x 10²⁴ atoms
e) 3.0 x 10²³ atoms

Can anyone explain this one?

Answers

(3 grams of carbon) x (1 mole of carbon/12 grams ) =3/12 = 1/4 of a mole of carbon. Then... ( 1/4 of a mole) x (6.02 x 10^23 atoms/mole) = approximately 1.5 x 10^23 atoms.

How did the color of the foxes’ environment change? Explain what happened to the foxes over many generations.

Answers

Answer:

The answer is below

Explanation:

1. With the aid of natural hues, the fox can change its color based on the environment it found itself in. For example, during summer and spring, fox color changes to dark to provide itself cover in the environment that is characterized by the brown dirt. Similarly, the fox color changes to white during winter and fall to blend with the snow.

2. In a bid to domesticate fox, it has been observed over many generations that the domesticated fox compared to wild fox has floppy ears and curly tails. The stress hormone level has reduced significantly and they possess a smaller adrenal gland.

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

What is the charge of the nucleus in an atom of oxygen-17?(1) 0 (3) +8
(2) –2 (4) +17

Answers

The charge of the nucleus in an atom of oxygen is +8. The correct option is 3.

What are the charges on the elements?

The charge is negative or positive or neutral charges present on the substance or molecule. The charges are produced by the gaining or losing of electrons.

The charges tell the tendency of the atom or molecule of gaining or losing of the atom.

Thus, the correct option is 3, +8.
