A gas isn’t heated from 298 k to 367 k while it’s volume changes from 2.5 L to 3.9 L. If the initial pressure of the gass is 1.1 atm , what is the final pressure of the gass
Answers
Answer with Explanation:
The "Boyle's Law" is also referred to as the "Mariotte's Law." This law shows the inverse relationship between the pressure of a gas and the volume of a container. This means that if the pressure is increased, the volume will decrease and vice-versa.
In the situation above, the plastic water bottle serves as the container. The little boy blew air into it, making the volume of the container increase. It carried the plastic ball with it, that's why it got stuck.
In order to remove the ball, the older brother will have to apply Boyle's law by compressing the plastic water bottle. His compression will increase the pressure in the container. This will allow the compressed air to rush out, thus moving the stuck ball with it. This will result into decreased volume in the container as well.
This is true, provided that both mass and temperature remain constant.
Answer:
by pushing down on the bottle to increase the air pressure inside the bottle
Explanation:
The pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
what is serap's momentum
what is the total momentum of the entire system?
Answers
1) David's momentum is 12,000 kg m/s east
2) Serap's momentum is 15,000 kg m/s east
3) The total momentum is 27,000 kg m/s east
Explanation:
1)
The momentum of an object is given by
where
m is the mass of the object
v is its velocity
In this problem, we have:
m = 600 kg is the mass of David+his dune buggy
is their velocity (taking east as positive direction)
Therefore, David's momentum is:
And the direction is the same as the velocity (east).
2)
Again, we can use the same equation:
where this time
m is the mass of Serap+dunebuggy
v is their velocity
In this problem,
m = 500 kg is the mass of Serap + dunebuggy
v = 30 m/s is their velocity (positive since it is also in the east direction)
Substituting, we find
And the direction is the same as the velocity (east).
3)
The total momentum of the entire system is given by
where
is David's momentum
is Serap's momentum
In this problem, we have the following data, found in the previous parts:
The two momentum have same direction (east), so we can simply add them together to find the total momentum:
And the direction is still East.

The four most common gases in dry air are nitrogen, oxygen, carbon dioxide, and water vapor.
The four most common gases in dry air are nitrogen, oxygen, carbon dioxide, and water vapor.
Nitrogen is the most abundant gas in dry air, making up about 78.6% of the air.
Oxygen is the second most abundant gas, accounting for approximately 20.9% of the air.
Carbon dioxide is present in small amounts, around 0.04%, but it plays an important role in the Earth's carbon cycle and climate. Water vapor, despite being a variable component, can make up around 0.5% of the air.
