A 2.0 L bag of potato chips in Denver is that 15 C0 print 82 ATM. The same bag is brought to the top of long peaks in the cold winter day. If the back and only spent 2.5 L before exploding and along peak has a temperature of negative 5C and a pressure of 0.45 ATM for the bag explode
Answer:
hello your question is poorly written below is the complete well written question
.A 2.0 L bag of potato chips in Denver is at 15oC and 0.82 atm. The same bag is brought to the top of Longs Peak on a cold winter day. If the bag can only expand to 2.5 L before exploding and Longs Peak has a temperature of -5oC and a pressure of 0.45atm, will the bag explode? Use the combined gas law to prove this to yourself
answer : The bag will explode
Explanation:
Given data :
Volume of bag ( v1 ) = 2 liters
Initial pressure ( p1 ) = 0.82 atm
Initial temp ( T1 ) = 15 + 273 = 288 k
Final Pressure on long peak (P2) = 0.45 atm
Final temp on Long peak (T2) = (273 - 5 ) K = 268 K
Determine the Final volume in long peak to know if the bag will explode
applying the gas laws
P1v1 / T1 = P2V2 / T2
V2 = p1*v1*T2 / p2 *T1
V2 = ( 0.82 * 2 * 268 ) / ( 0.45 * 288 )
= 3.39 Liters
since final volume ( V2 ) > ( v1 ) the bag will explode

What type of molecule would deviate the most from ideal gas behavior?
Answer:
molecule at low temperature and high pressure
Explanation:
this is because two of the postulates of kinetic theory of gases hold true only when there is low pressure and high temperature. as the pressure goes on increasing and temperature goes on decreasing, a molecule will deviate from ideal behavior.
If the pressure of a gas at constant volume is 4.5 atm at 100 °C, wh
will the pressure be if the temperature is changed to 350 °C?
Answer:
New pressure = 7.51 atm
Explanation:
Given that,
Initial pressure, P₁ = 4.5 atm
Initial temperature, T₁ = 100°C = 100+273 = 373 K
Final temperature, T₂ = 350°C = 350 + 273 = 623 K
We need to find the new pressure. Using the below relation as follows :
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{4.5\times 623}{373}\\\\P_2=7.51\ atm[/tex]
So, the new pressure is 7.51 atm.

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.

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.

A gardener cut her finger while pruning shrubs. She noticed that after two weeks the wounds had nearly healed with just a small scar remaining. Which statement describes what will happen next?
A. Each one of the individual cells near the wound will grow in size to cover the injured part.
B. Cells will be transported from distant areas to the wound to cover the injured area.
C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.
D. A material will be released by the injured cells that will cover the wound and repair the cells.
Answer:
c
Explanation:
The wound will be healed by the production of new cells near the wound by the cell replication process and the therefore the identical cells are produced by the mitosis to repair the damaged tissues.
Note the below points about mitosis;
The mitosis is a process in which the cell replication occurs.In mitosis, the single parent cell is divided into two identical daughter cells by the process of cell division, it takes by time.The mitosis involves the healing of wound, growth of the organisms, replacement of the worn out cells.Thus, mitosis is the process involved in the healing of wound in living beings.
Therefore, we can say that the answer of the question is C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.

Question 1 options:
revolution, gravitational
rotate, gravitational
gravitational, rotate
gravitational, revolution
Gravitational force is the force between the sun and the Earth keeps the Earth in its orbit. The period of revolution is the time it takes for Earth to complete one orbit.
What is gravitational force?Gravitational force is a kind of attraction force which acts between the two bodies.
Sun's gravitational force is a 3 dimensional attraction force under which earth is present. And due to centripetal force of sun, orbit of earth is present in the stationary state. Earth revolves around the sun to complete one round of orbit and this motion is known as revolution of earth.
Hence, gravitational force is present between the sun and the earth, and revolution is the time to complete one orbit.

“Nature vs. nurture” is a debate about
A
whether a trait is learned or inherited.
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.
