What happens to metal when exposed to hot and cold?
When metal is exposed to heat, it expands and when exposed to cold, it contracts. These changes in temperature can cause the metal to warp, crack, or weaken over time due to repeated expansion and contraction. Extreme temperature fluctuations can also affect the structural integrity of the metal.
What happens to the skin when it gets cold?
When skin gets cold, blood vessels constrict to conserve heat and reduce blood flow to the skin's surface. This can lead to a pale appearance and make the skin feel cold to the touch. Prolonged exposure to cold temperatures can also cause skin damage, such as frostbite.
What happens when something gets cold?
When something gets cold, its molecules slow down and move closer together, causing the material to contract and become more dense. The decrease in temperature can also affect the electrical conductivity and chemical reactions of the material.
What happens to matter when it gets cold?
When matter gets cold, its particles slow down and may come closer together, leading to a decrease in volume. In some cases, cold temperatures can cause matter to undergo phase changes, such as from a gas to a liquid or solid. Materials may become more rigid and brittle as they lose thermal energy.
What is the primary disadvantage of hard steel?
As steel gets harder, it also gets less flexible.
What happens when air conditioner touches steel?
The steel gets cold.

What happens when a Lcd tv get frozen?
it gets a cold
What happens to birds when it gets cold?
They migrate to the south.
What happens to a human when it gets very cold?
they can die
Which has higher density cold steel or hot steel?
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
What happens when a fluid starts to cool down after being heated?
it gets coldit gets cold
What happens when ice is added to water?
its gets cold Actually the ice gets warmer. Its the water that gets cold.
