How high can a balloon go?
Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop.
What is the common unbalanced force acting on an object in motion?
Common forces that are often unbalanced include the force of gravity and applied forces. When these forces are unbalanced, objects accelerate, change their position and find new configurations for which all forces are again balanced. The weight of an object is the force exerted by gravity on that object.
What happens when we press a rubber ball placed on a table?
When the rubber ball placed on the table is pressed then it gets deformed due to the force acting on it. The extent of deformation of the rubber ball will depend on the softness of the rubber and the pressure applied on it.
How does the shape of a rubber ball change?
Though rubber ball changes shape by pressing with hand, still it can be said to be solid as it follows the properties of solid which state that the atoms should be closely bonded in the material firmly with each other though they can move some bit to change the shape.
Can you change the shape of sponge?
A sponge can change its shape by pressing but it is a solid.
What changes the shape of a sponge?
the shape of the material sponge change when it zapped with light.
What happened to the box and to the house when you stretch the rubber band?
Answer: the box will move with the rubber band when you keep pulling it.
What happens when you stretch the rubber bands will it become longer or shorter Why?
The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
How long does thermoplastic rubber last?
10 years
Does synthetic rubber have a shelf life?
Per the Rubber Manufacturer’s Association (RMA) findings, heat and moisture are the most common hazards to affect sheet rubber in the warehousing environment….Shelf Life for Rubber Products.
| COMMON / TRADE NAME | TYPE OF RUBBER POLYMER | RECOMMENDED SHELF LIFE |
|---|---|---|
| Natural Rubber | 3-5 years | |
| SBR | Styrene-butadiene | |
| Synthetic Natural Rubber | Polyisoprene |

How is rubber stored?
1. Storage areas for rubber products should be kept cool and dry. The temperature of the storage area should not exceed 68° F. / +20° C., or go below 14° F. / -10° C. All rubber materials must be stored away from heat producing equipment and/or heating devices.
Where do you store rubber?
How To Store Tire Bladders and Rubber Parts
- Store rubber parts in opaque containers to avoid exposing them to light.
- Rubber parts should be stored away from circulating air and sources of ozone.
- Storage area should remain dry, below 75% relative humidity and at temperatures above 5° C (41°F) and below 38°C (100°F).
How do you preserve rubber?
To keep your rubber from cracking, it’s all about storage and conditioning.
- Store rubber at room temperature.
- Avoid exposure to UV light.
- Wash rubber with gentle cleaners.
- Keep conditioning to a minimum to restore softness.
- Store rubber objects in airtight containers.
