Can rubber stand the cold?
If you drop a piece of rubber in liquid nitrogen, (in a dewar, where the liquid nitrogen does not boil that fast), then the rubber will be frozen. In that sense, the rubber will get hard and brittle. If by 'freeze' you mean the formal definition, which is to form actual crystals, as water does when it freezes, then the rubber won't freeze. You should know that when you drop the rubber into the liquid, the liquid will boil off very quickly for a while even though it's in a dewar. That's because heat will flow straight from the rubber into the liquid.
How long does it take for heat to expand the length a rubber band stretches?
A relaxed rubber band seems like it should expand when heated but in fact it will contract due to the increase in the tension of the rubber band. The force of tension in a rubber band can be modeled by Hooke's Law:F = -kxwhere k the spring constant is directly proportional to the temperature. According to Hooke's law a stretched rubber band should have an increase in tension when heated. However a stretched rubber band cannot contract until its let go and by Hooke's law there is no tension on a relaxed spring so how can there can be any contraction? Well, tension is derived from the change in Entropy by heating the rubber band. Entropy is a way of measuring the amount of 'disorder' in a system. The rubber band can be looked as a string of molecules. So when the string is all laid out it is has low 'disorder'. If the string is all balled up it has high 'disorder'. So if rubber band is heated the Entropy increases which pulls the string of molecules into a ball. This increase the tension in a relaxed rubber band which causes it to contracts it.
How do you make metal contract?
They expand ------- No, normally metals expand when heated.
Why rubber is the best material to make balloon?
Natural rubber latex provides the most elasticity and it is highly permeable. These qualities make balloons made from rubber capable of being flexible, as well as able to be dyed easily.
Does temperature affect the elasticity of a rubber band'?
no it does not change the elasticty if any thing it makes the rubber band smaller.What effect does heat have on the elasticity of rubber?That is not an easy question to answer but the heat stretches the rubber band because the molecules have to arrange or move themselves around. When a rubber band isn't being stretched the molecules are in a srtaight line.
How can I expand rubber effectively?
To expand rubber effectively, you can heat it to a high temperature. This causes the rubber molecules to move more freely and expand. Another method is to mix the rubber with a blowing agent, which releases gas when heated, causing the rubber to expand.
Does Hot water shrink rubber?
No it will cause rubber to expand.
Why can kerosene expand a rubber band?
Well, isn't that a happy little question! When kerosene comes into contact with a rubber band, it can cause the rubber molecules to swell and expand. This happens because the kerosene is able to penetrate the rubber band, loosening the bonds between its molecules and allowing them to spread out. Just like when we paint happy little trees, sometimes unexpected interactions can create beautiful results!
Does heating up a rubber band make it more stretchy?
Yes, heating up a rubber band can make it more stretchy because heat causes the polymer chains in the rubber band to expand and move more freely, allowing the rubber band to stretch further. However, excessive heat can also degrade the rubber band and make it less elastic over time.
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.
What is a good sentence for the word expand?
This rubber band expands when I put it in my hand.

Why does a balloon expand when you blow in it?
When you blow air into a balloon, you are increasing the pressure inside the balloon. This increase in pressure causes the rubber of the balloon to stretch and expand, filling up with the air you are blowing in. The elastic nature of the rubber allows the balloon to expand and hold the air inside it.
Why is rubber a good ear defender?
It will expand to fit the ear to close all inputs
If heat is added to a rubber band what happens?
When heat is added to a rubber band, the rubber band will expand and become more flexible. This is because the heat causes the rubber molecules to move around more freely, allowing the rubber band to stretch more easily.
Why a lot of air can be contained in a vehicle tire?
that's because the tires of a vehicle is rubber, and it can expand.
Why do balloon's full of air get bigger when placed in a warm oven?
because the rubber and the air expand .
