Explain why a helium weather balloon expands as it rises in the air Assume that the temperature remains constant?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand.
The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.
What else can I help you with?
What will change the size of the weather balloon as it rises?
The pressure of the air inside it. The higher the balloon rises, the lower the outside air-pressure. With less pressure outside, the balloon expands because of the pressure of the air inside it. Eventually, the balloon bursts, and scientists recover the instruments when they fall to earth.
How much air can a water balloon hold?
The amount of air a water balloon can hold depends on its size and how tightly it is inflated. As the balloon expands with air, the water inside compresses, allowing more air to be added. However, there is a limit to how much air a water balloon can hold before it bursts.
What are the effects of a warm temperature on gas particles?
when the temperature is warm, the particles move faster and the gas is expanding and pushing on the walls of the item, like for example, a NYPD float balloon. If the gas expands too much, the balloon will explode
When a parcel of air moves upward it expands and cools?
Yes, as a parcel of air rises, it moves into regions of lower pressure where it expands. As the air expands, it does work against the surrounding pressure, causing a decrease in its temperature, a process known as adiabatic cooling. This cooling can lead to condensation and cloud formation if the air reaches its dew point temperature.
Is air matter how can you tell-?
Yes it is, because when you blow air into a balloon, the balloon expands meaning it takes up space.
What is the independent variable of Charles law balloon?
In Charles's Law experiments involving a balloon, the independent variable is the temperature of the gas inside the balloon. As the temperature increases, the volume of the gas also increases, assuming the pressure remains constant. This relationship illustrates how gas expands when heated, demonstrating the principles of Charles's Law.
Ideal gas law to explain why a hot air balloon floats?
We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
Will a difference in air temperature affect the size of a balloon?
Yes, a difference in air temperature can affect the size of a balloon. When air temperature increases, the air inside the balloon expands, causing the balloon to inflate. Conversely, when air temperature decreases, the air inside the balloon contracts, causing the balloon to deflate.
How does the volume in a hot air balloon change?
The volume of a hot air balloon increases as the air inside the balloon expands when it is heated. As the balloon ascends and the air temperature decreases, the volume of the air inside the balloon decreases as well. The pilot can control the altitude of the balloon by controlling the temperature of the air inside.
Why do most balloons burst as they ascend high altitude?
The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.
How does temperature affect the gas in a balloon?
Temperature affects the gas in a balloon by changing the volume of the gas inside. As temperature increases, the gas molecules move faster and take up more space, causing the balloon to expand. Conversely, a decrease in temperature causes the gas molecules to slow down and the balloon to shrink.
Why balloon kept in sun burst after some time?
pressure x volume divided by temperature is a constant (Boyle's Law), or PV/T = constant. Since pressure does not change, as temperature increases so must the volume, so the balloon expands
Which law is obeyed when a balloon pops due to sun rays?
Charles's law. Pressure acting on the balloon is constant(atmospheric pressure). Thus when the sun's rays heat the balloon, the air inside expands and it pops sooner or later.
Does a balloon expands or contract when put in the refrigerator where it is cold?
A balloon will contract when placed in the refrigerator because the cold temperature slows down the air particles inside the balloon, causing them to decrease in volume.
How does Charles law make a balloon rise?
Charles' Law states that as temperature of a gas increases, its volume also increases if pressure remains constant. When a balloon is heated, the air inside it warms up and expands, causing the volume of the gas to increase. This increase in volume causes the balloon to rise because it becomes less dense than the surrounding air.
What happens to the pressure of the air inside the balloon if the volume remains constant if the balloon is heated?
Pressure increases.Take a look at the relationship:PV=nRTR is a constant. n is the amount of gas, which would be held constant in a sealed balloon. So:P1 V1 / T1 = P2 V2 / T21- before2- afterThis algebraic equation can help predict the outcome of other cases as well.taking just the balloon first, it is a solid body(flexible), on heating it undergoes cubical expansion, so the first thng that happens is the container(balloon) expands so untill a particular expansion of it the volume of air inside increases(gases dont have a fixed volume) they occupy the area they have .
What happens when you add heat to a balloon filled with air?
The balloon expands.
