how does latitude affect the temperature in an area
Answer:
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.

Most hot air balloons are round. Yes, you can have some other shapes like this one, but its shape is still rounded. Using the assumptions, explain why a square hot air balloon would be hard to make.
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.
What is a hot air balloon ?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.

At a constant temperature the pressure on a 10.0L sample of gas is charged from 1140 torr to 1.00 atm. What is the new volume of gas sample?
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
“Nature vs. nurture” is a debate about
A

B
the traits of plants vs. the traits of animals.
с
whether animals can teach humans new traits.
D
whether a trait was acquired outdoors or indoors.
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.
What are learned traits ?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.

A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0 C. What will the volume of the balloon be if the temperature is increased to 80.0 C and the pressure remains constant? (Hint: Use the Charles law equation)
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.

A scuba diver swims deeper and deeper into the ocean. What happens to the nitrogen in her blood as she goes deeper
Answer:
it compresses under the pressure.
Explanation:
when she comes up, it will re-expand as pressure goes down- this is why they have to be very careful how fast they come back up.
Answer:
If a diver goes through too great of pressure change too quickly, their body cannot eliminate all of the expanding nitrogen and the excess nitrogen forms bubbles in their tissues and blood. These nitrogen bubbles can cause decompression sickness (DCS) by blocking blood flow to various parts of the body, causing strokes, paralysis, and other life-threatening problems.
