They expand in heat to allow blood to reach the extremities to be cooled..
Exactly the opposite is true when there cold.. Blood is drawn away from the extremities to help keep vital organs warmer.
Heat causes expansion.
Muscles expand and contract as a way to produce heat for the body.
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
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
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.
Cold causes matter to contract. Heat causes matter to expand.
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.
heat makes metal expand.
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
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.
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.
Because heat makes things expand, and cold makes things contract.("'\(o.o)/"')
To allow them to expand and contract with heat and cold. Without those, the road would end up buckling.
It will cause the liquid to either expand or contract.
because they expand and contract with heat.
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.
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.
