Answer:

Increases.

Explanation:

Temperature is the measure of the average kinetic energy of a system. As temperature increases, so will kinetic energy. As kinetic energy increases, speed increases.

A square hot air balloon would be hard to make because the round shape of traditional hot air balloons allows for even distribution of heat, which is necessary to maintain the balloon's lift and stability.

A hot air balloon is a balloon filled a heated air which can rise above the atmosphere. In a round balloon, the heat from the burner is evenly distributed around the circumference of the balloon, causing the air inside to heat up and rise, which in turn causes the balloon to lift.

If a hot air balloon were to be made in a square shape, the heat would be distributed unevenly and concentrated in certain areas. This could cause the balloon to become unstable, as the hot air would rise in some areas but not others, leading to uneven lifting and potential loss of control.

Additionally, the corners of the square shape would be more susceptible to damage and could create weak points in the structure of the balloon.

Therefore, while it is possible to create hot air balloons in other shapes, the traditional round shape has been found to be the most effective and efficient for maintaining the necessary heat distribution and stability required for safe and successful flight.

Answer:

Letter A

whether a trait is learned or inherited

Explanation:

The nature versus nurture debate involves the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) influences. Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.

The debate called Nature vs. nurture is about whether a trait is learned or inherited. This is an investigation on learned traits and nurtured traits in humans. Thus option A is correct.

All living things are learning something during their growth. These learning mold up one's personality and cannot be created by birth. Like the good characteristics we are learning from schools. These behaviors are called learned traits.

Some traits or behaviors are created by birth itself and they are called natural traits. The nature versus. nurture debate is a philosophical, scientific, and cultural discussion about whether human culture, conduct, and personality are largely influenced by nature or nurture.

Environment, culture, and experience are the most prominent definitions of nurture in this discussion, whereas nature is frequently regarded as genetic or hormone-based behaviors, characteristics, and dispositions.

Answer:

The mass is 20, 89 grams of He.

Explanation:

We calculate the weight of 1 mol of He, from the atomic weight of each element obtained from the periodic table: Weight 1 mol He= 4, 0020602 g. 1 mol He-----4, 0020602 g. 5,22 mol He---x= (5,22 mol He x4, 0020602 g)/ 1 mol He= 20, 89 g

hope this helps also can i get brainliest

The mass of 5.22 mol of He will be 20.84 grams.

We have 5.22 mol of He.

We have to calculate its Mass.

Helium is a chemical element with the symbol He and atomic number 2. It is a gas which is colorless, odorless, tasteless, non-toxic, inert and monatomic.

According to the question -

Number of moles of Helium = 5.22 mol

Now, I mole of Helium will have its mass equal to its Atomic weight. Therefore -

Mass of 1 mole of He = 4.002602 g

So, the mass of 5.2 mol of He will be = 5.2 x 4.002602 = 20.84 grams

Hence, the mass of 5.22 mol of He will be 20.84 grams.

Answer:

The final volume of the balloon is 24.480 liters.

Explanation:

Let consider that no leakages occur in the balloon during the isobaric process and that helium behaves ideally. From Equation of State for Ideal Gases, we construct the following relationship:

[tex]V_{o}\cdot T_{o} = V_{f}\cdot T_{f}[/tex] (1)

Where:

[tex]V_{o}[/tex], [tex]V_{f}[/tex] - Initial and final volume, measured in liters.

[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperature, measured in Kelvin.

If we know that [tex]V_{o} = 30\,L[/tex], [tex]T_{o} = 288.15\,K[/tex] and [tex]T_{f} = 353.13\,K[/tex], the final volume of the balloon is:

[tex]V_{f} = \frac{V_{o}\cdot T_{o}}{T_{f}}[/tex]

[tex]V_{f} = 24.480\,L[/tex]

The final volume of the balloon is 24.480 liters.

Answer:

15 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 10 L

Initial pressure (P₁) = 1140 torr

Final pressure (P₂) = 1 atm

Final volume (V₂) =?

Recall:

1 atm = 760 torr

The new (i.e final) volume of the gas can be obtained as follow:

Initial volume (V₁) = 10 L

Initial pressure (P₁) = 1140 torr

Final pressure (P₂) = 760 torr

Final volume (V₂) =?

P₁V₁ = P₂V₂

1140 × 10 = 760 × V₂

11400 = 760 × V₂

Divide both side by 760

V₂ = 11400 / 760

V₂ = 15 L

Therefore, the new volume of the gas is 15 L

Latitudes are used to indicate a precise location of any feature on the earth's surface.

Temperature changes with latitudes .At higher latitudes, the Sun's rays are less direct. The farther an area is from the Equator, the lower its temperature. At the poles, the Sun's rays are least direct.Near the equator sun's rays are perpendicular resulting into very high temperatures. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.
