🔥Heating water increases the kinetic energy of water molecules, causing them to move faster.
💨When water molecules gain enough energy, they undergo vaporization and transform into steam.
💦Steam is the gaseous state of water and is invisible, unlike the mist we commonly refer to as steam.
🌡️Water can reach temperatures higher than 100 degrees Celsius when vaporized.
🔥Water vapor can be easily extinguished by fire due to its lower temperature compared to the ignition point of the flame.
What happens to water molecules when they are heated?
—Heating water increases the kinetic energy of water molecules, causing them to move more quickly.
What is vaporization?
—Vaporization is the process by which a liquid, such as water, changes into a gas, like steam, due to an increase in temperature.
Is steam visible?
—No, steam is actually invisible. The mist we commonly refer to as steam is not steam, but rather tiny droplets of liquid water suspended in the air.
Can water reach temperatures higher than 100 degrees Celsius?
—Yes, when water is in the gaseous state as steam, it can reach temperatures higher than 100 degrees Celsius.
Why does fire extinguish when it comes into contact with steam?
—Water vapor, which is hotter than its boiling point, quickly absorbs heat from the flame, causing it to cool down and extinguish.
