Why are some balloons able to float while others are not able to?
In order to float, a given mass (or volume) must be lighter than the equivalent mass that surrounds it. In other words, it must lighter than air. Filling a balloon with the same air that surrounds it will mean it cannot possibly be lighter than air (at best it will be the same weight). But the weight of the balloon alone will make it heavier. It therefore makes sense to construct the balloon from the lightest possible material. Rubber is quite heavy but it is also elastic -- thus the air inside is compressed. Thus even the air inside would be heavier than the equivalent mass of uncompressed air outside. Therefore it also makes sense to use a material that does not stretch. In order to make the balloon float, we must fill it with a gas that is not as dense as the air that surrounds it. Helium is ideal because the molecules are spread out much more than the molecules in the surrounding air -- and is therefore lighter (fewer molecules means less weight for a given mass of gas). Moreover, the material used in helium-filled balloons ("party" balloons) is wafer-thin and extremely light. It also doesn't stretch as easily as rubber, so the helium is not compressed. Thus the balloon easily floats upwards with very little helium. The same effect can be achieved simply by warming the air inside the balloon. This forces the gas to expand, increasing the balloon's mass but without increasing its weight. With sufficient mass, the balloon eventually becomes lighter than the equivalent mass of the surrounding air -- and begins to float upwards. Filling a rubber balloon with helium is also possible, provided the balloon is small enough to begin with (making it lighter), and elastic enough to accommodate the amount of helium required to overcome the balloon's overall weight. The helium will be compressed, however, thus much more helium is required to increase the mass sufficiently to overcome the density of the surrounding air -- far more helium than is required in a normal helium-filled "party" balloon.
Does heat expand rubber?
Whether a material expands or contracts when it is heated can be ascribed to a property of the material called its entropy. The entropy of a material is a measure of the orderliness of the molecules that make up the material. When the molecules are arranged in an ordered fashion, the entropy of the material is low. When the molecules are in a disordered arrangement, the entropy is high. (An ordered arrangement can be thought of as coins in a wrapper, while a disordered one as coins in a tray.) When a material is heated, its entropy increases because the orderliness of its molecules decreases. This occurs because as a material is heated, its molecules move about more energetically. In materials made up of small, compact molecules, e.g., the liquid in a thermometer, as the molecules move about more, they push their neighbouring molecules away. Rubber, on the other hand, contains very large, threadlike molecules. When rubber is heated, the sections of the molecules move about more vigorously. In order for one part of the molecule to move more vigorously as it is heated, it must pull its neighbouring parts closer. To visualize this, think of a molecule of the stretched rubber band as a piece of string laid out straight on a table. Heating the stretched rubber band causes segments of the molecules to move more vigorously, which can be represented by wiggling the middle of the string back and forth. As the middle of the string moves, the ends of the string get closer together. In a similar fashion, the molecules of rubber become shorter as the rubber is heated, causing the stretched rubber band to contract
What makes a balloon deflate hot water or cold water or cold water?
Cold water causes a balloon to deflate because the cold air the cold water releases is more dense than the hot air hot water releases. Take a hot air balloon for example, the flames cause the air in the balloon to heat up, causing the hot air balloon to rise. In order to make the balloon go down, you slowly turn on and off the flames in order to cool the air already inside the balloon over a period of time.All in all, cold waters causes balloons to deflate.P.S. Sorry if that made absolutely no sense, it's rather difficult explaining these types of things. c:
What substances are the best insulators?
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
Will a water balloon drop from 6 feet make a larger splat than a water balloon drop from 1 foot?
1 foot
What did James Glaisher make his balloon with?
James Glaisher made his balloon with silk fabric coated in rubber to make it airtight. The balloon was filled with hydrogen gas for buoyancy.
How do you make it harder for a balloon to pop?
To make it harder for a balloon to pop, you can try inflating it less so there is less internal pressure, using a thicker balloon material, or keeping it away from sharp objects or rough surfaces. Additionally, avoiding overinflating the balloon and handling it gently can also help prevent it from popping.
How do you make your own hair tie?
To make your own rubber hair tie, you need a balloon and scissors. First, cut the top off of the balloon. Discard the top of the balloon. Now, cut the balloon neck into strips about 1 cm thick. You can use these strips as hair ties, or rubber bands.
How do you make a newton scooter without a balloon?
use a rubber band or an elastic
How do you make rubber as a conductor?
Rubber is an insulator, not a conductor. To make rubber conductive, it can be mixed with a conductive material like carbon black or metal particles. This creates a composite material that allows the rubber to conduct electricity.
What would happen to a completely inflated balloon if it were taken from the inside a house to the outside in the middle of -15 Celsius?
The cold temperature outside would cause the air inside the balloon to contract and decrease in volume, leading to the balloon deflating. The rubber material of the balloon may also become more brittle in the cold, which could make it more prone to popping or breaking.
What material is grown to make natural rubber?
latex
What causes a balloon to pop in a freezer?
When a balloon is placed in a freezer, the air inside it contracts and the balloon becomes more rigid. If the balloon is already stretched to its limit, the increased pressure from the contracting air can cause it to pop. Additionally, extreme cold temperatures can make the rubber of the balloon more brittle, increasing the likelihood of it breaking.
What material is used to make an air balloon?
The gas is hot air.
Why rubber is suitable to make balloons?
Rubber is suitable for making balloons because it is lightweight, stretchable, and elastic. These properties allow the balloon to expand when filled with air or helium and retain its shape. Additionally, rubber is airtight, which helps the balloon to hold the gas for an extended period of time.
Does a latex balloon stick more than a helium balloon?
Latex is the material a balloon can be made of. Helium is a gas that a balloon can be filled with. The question does not make sense. Please restate the question.
What is the material use to make it the baton?
Metal and rubber
