What is special about water?
Water’s importance to life functions all attribute to its polarity, hydrogen bonding and density. Water is a polar molecule: constructed of one oxygen atom and two hydrogen atoms, the oxygen is considerably more electronegative than the hydrogen.
Why is water a special chemical?
The chemical composition of water is H2O – two hydrogen atoms and one oxygen atom. The properties of water are special because of the way its atoms bond together to form a water molecule, and the way the molecules interact with each other.
Why is water unique from other liquids?
In the liquid form, the hydrogen atoms of one water molecule are attracted to the oxygen atom of another molecule. Each water molecule can form up to four of these hydrogen bonds and, collectively, they give water a cohesiveness unique in liquids.
What liquids dont contain water?
Non-water based liquids like cooking oils, kerosene, mineral turpentine, paraffin oil and oil based paints are less frequently identified. Evidence suggests that students freely associate liquids with water or assume they all contain some water because they are a liquid.
Is ice still H2O?
Ice is made from water just like steam or liquid water. However water is not made from steam or ice, it’s made from water. Water is the compound, ice or steam is the state of the matter; ie., solid and gaseous, respectively. Ice IS considered to be water – just water in the solid phase.
Is ice water bad for?
There is little scientific evidence to suggest that drinking cold water is bad for people. In fact, drinking colder water may improve exercise performance and be better for rehydration when exercising, especially in hotter environments.
Can ice be called water?
Ice is water in its frozen, solid form. Ice often forms on lakes, rivers and the ocean in cold weather. It can be very thick or very thin. It occurs as frost, snow, sleet and hail.
What did you feel when you touch the ice cube?
Answer; When we touch an ice cube we fill cold since the ice cube is a water that been frozen in a freezer. Anything frozen feels cold because of its temperature. Anything you touch that is required heat it feels hot due to each temperature.
Can ice be stronger than diamond?
You are correct in stating that ice’s official “hardness”, as measured on the “Moh’s scale of hardness of minerals”, is only 1.5. The hardness of minerals ranges from 1 (for talc, to 10 for diamond”. Practically all minerals are technically harder than ice.
How strong can ice get?
Ice can never be as strong as most metals but it can get extremely strong when super cooled, an example is ice on the surface of most jupiter and neptune moons, the ice there at -190 degrees Celsius is as hard as a granite rock.
What is the hardest ice can get?
According to this link the hardness of ice at -70 C is 6, which is about the same as quartz. However, it’s unclear if that refers to the average ice you find out in nature, or ice made from demineralized water, which is harder because it has no impurities to weaken the bonds.
What is the coldest thing on earth?
A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). This is the closest a substance of this mass and volume has ever come to absolute zero.
Is ice harder than concrete?
Mineral content in water will affect hardness as well as temperature. In general though, ice will rate somewhere around 1.5 Mohs. On he same scale, youd like concrete to be in he 5-7 Mohs range. So, yes, in general concrte is harder than ice.
