What else can I help you with?
Does gold expand under hot or cold water?
Heat causes expansion.
Why do humans shiver when cold?
Muscles expand and contract as a way to produce heat for the body.
Why do hot beakers crack in cold wale?
im assuming you meant to type water... this happens because heat makes things expand, whilst cold makes things contract. by putting a hot beaker in cold water, you put too much strain on the beaker because it is changing size so fast
What would happen if there were no gaps in a bridge?
Expansion and contraction with heat and cold causes the road to swell and shrink. the gaps are for that purpose so the road or bridge would buckle and break if they were not there! Before this was discovered things broke often
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 does matter react to cooling?
Cold causes matter to contract. Heat causes matter to expand.
How temperature weather rocks?
Rocks expand due to heat and contract due to cold. Thus, due to unequal expansion and contraction ,the rocks tend to break and get weathered. Rocks expand due to heat and contract due to cold. Thus, due to unequal expansion and contraction ,the rocks tend to break and get weathered.
Why do oven trays expand and contract?
heat makes metal expand.
Why do concrete patios crack?
A concrete patio usually cracks due to heat cold. If it is to cold it contract and break. If it is to hot it will expand and break. Then water can seep into those cracks and freeze causing the crack to expand
Do water pipes in homes expand and contract?
Yes, water pipes in homes can expand and contract due to changes in temperature. When pipes are exposed to heat, they expand, and when they cool down, they contract. This expansion and contraction can lead to stress on the pipes, potentially causing leaks or damage over time.
Why do object expand?
Objects contract or expand depending on the temperature. Cold makes things contract, heat makes things expand. However, there are some exceptions. For example, water expands when it turns to ice. This is due to the process of crystallization. The reason that objects expand and contract is found at the atomic level. When an object is warm, its molecules move faster and spread out, making that object expand. However, when an object is cold, the atoms slow down and move back together, making the object contract.
Why do hot atoms move colder than warm atoms?
Because heat makes things expand, and cold makes things contract.("'\(o.o)/"')
Why do roads over bridges have small gaps in them?
To allow them to expand and contract with heat and cold. Without those, the road would end up buckling.
What is the effect of heat on liquids?
It will cause the liquid to either expand or contract.
Why do sidewalks have lined joints built into them?
because they expand and contract with heat.
Why shrinkage comes in injection molding machine?
you know heat makes something expand and cold makes it contract. When injection molding the plastic material is hot, so it expands and when it is cold it shrinks. That is why how shrinkage comes.
You just drove through water and now your car is making a rattling noise like there is a loose bolt?
It is a heat shield on your exhaust pipe or muffler. The hot pipe when splashed by cold water cause the metal to expand and contract so quickly the weld cracked off and the heat shield now rattles It is a heat shield on your exhaust pipe or muffler.
