Chemical Bonding
Chemical bonding is the attractive force that holds atoms together in atomic groupings. Atoms that achieve stability by sharing electrons with other atoms are linked by a covalent bond.
Water
Water remains liquid at room temperature, whereas other similar substances are immediately converted into gases.
- The density of water increases to abnormally high temperatures from 0 to 4°C, reaching a maximum value of 1000 kg/m3. Above or below these temperatures, water expands, and its density decreases.
- In its solid state, water floats on liquid water, contrary to what occurs with other substances.
- Water is an excellent heat storage medium. Its resistance to increasing or decreasing its temperature is higher than that of other liquids or
