Why does the balloon stop blowing when doing the experiment?
When doing the balloon experiment, the balloon stops inflating when the pressure inside the balloon equals the pressure of the gas being released from the reaction in the container. This equilibrium is reached when the forces pushing the gas out of the container are balanced by the forces keeping the gas inside the balloon.
When two forces act on an object in opposite directions in a closed balloon the foresc are?
When two forces act on an object in opposite directions inside a closed balloon, the forces are in equilibrium. This means that the net force on the object is zero, resulting in no acceleration of the object.
What is the effect of forces exerted on a balloon when it is squeezed?
When a balloon is squeezed, the forces exerted on it cause the air inside the balloon to be compressed. This compression increases the pressure inside the balloon, leading to a change in the balloon's shape and size. If the squeezing force is too strong, it can cause the balloon to burst.
How does bouyancy lift a balloon?
Buoyancy lifts a balloon due to the difference in density between the air inside the balloon and the surrounding air. The balloon is filled with a gas that is less dense than the air, creating an upward force. This force, known as buoyant force, pushes the balloon upwards until it reaches a point where the forces are balanced and the balloon can float.
How do chemicals affect the inflation of a balloon?
Chemicals such as baking soda and vinegar can react to produce carbon dioxide gas, which can inflate a balloon by increasing pressure inside it. When the reaction occurs in a closed environment like a balloon, the increasing pressure forces the balloon to inflate.
Is a hot air balloon a balanced or unbalanced force?
A hot air balloon is balanced because the upward lift force from the hot air inside the balloon is equal and opposite to the downward force of gravity on the balloon and its contents. This balance allows the hot air balloon to float in the air.
What are the molecular forces keeping a balloon inflated?
The gas molecules inside the balloon collide with the walls of the balloon, creating pressure that pushes against the balloon's surface and keeps it inflated. This is due to the kinetic energy of the gas molecules in constant motion.
What forces are used in a hot air balloon?
In a hot air balloon, buoyant force (lifting the balloon due to the density difference between the hot air inside the balloon and the cooler air outside) and wind force (pushing the balloon in a particular direction) are the primary forces involved in its movement. Additionally, the pilot can control the vertical movement using the burner to heat the air inside the balloon.
WHAT ARE THE TWO FORCES ACTING ON THE hot AIR BALLOON?
The two main forces acting on a hot air balloon are buoyant force, which lifts the balloon due to the density difference between the hot air inside the balloon and the cooler air outside, and gravity, which acts to pull the balloon downward.
What two forces act on the hot air balloon?
Two forces that act on a hot air balloon are lift, generated by the heated air inside the balloon being less dense than the surrounding air, and gravity, which pulls the balloon downward.
Is pressure in a balloon less than atmospheric pressure?
Yes, the pressure inside a balloon is typically slightly higher than atmospheric pressure to keep the balloon inflated. When a balloon is fully inflated, the pressure inside the balloon is balanced by the tension in the balloon's material, which allows it to maintain its shape.
Why does an inflated balloon stick to a wall?
When an inflated balloon is pressed against a wall, the air inside the balloon gets compressed, creating a higher pressure inside the balloon. This higher pressure forces the balloon to stick to the wall due to the imbalance of pressures pushing against the wall.
