Answer:
1)Two atoms of the same chemical element are typically not identical. ... Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.
2)Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of water drops below zero degrees Celsius as you apply pressure. ... For most liquids, applying pressure raises the temperature at which the liquid freezes to solid.
3)Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right. To accelerate the burning of diamond, you can give it more heat and more oxygen.
4)Alcohol reaches your brain in only five minutes, with immediate effects appearing within 10 minutes. After 20 minutes, your liver begins processing the alcohol. On average, the liver can metabolize 1 ounce of alcohol every hour
5)When glass is made, the material (often containing silica) is quickly cooled from its liquid state but does not solidify when its temperature drops below its melting point. At this stage, the material is a supercooled liquid, an intermediate state between liquid and glass.
6)Anything that tastes sour – from vinegar (acetic acid) to sour cream (lactic acid) – has acid. Even strong acids can be safe in low concentrations.
Explanation:
Answer:
1.No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different
2.Yes, water can stay liquid below zero degrees Celsius. ... When we apply pressure to a liquid, we force the molecules to get closer together. They can therefore form stable bonds and become a solid even if they have a higher temperature than the freezing point at standard pressure.
3.Diamond can indeed be set on fire since it is made of carbon. ... Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right
4.Alcohol has a profound effect on the complex structures of the brain. It blocks chemical signals between brain cells (called neurons), leading to the common immediate symptoms of intoxication, including impulsive behavior, slurred speech, poor memory, and slowed reflexes.
