Does Water Make Grease Fires Worse?
Water and oil do not mix (immiscible liquids) because water is polar and grease oil is non-polar. They do not form intermolecular bonds and instead repel each other. There is a separation of oil and water layers. The denser liquid falls...

Why Does Water Evaporate at Room Temperature?
Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...

Can Metals Exist as Gases?
Yes, metals can exist in gaseous forms. To illustrate, let's consider lead, which has a boiling point of 1740°C. When heated past its melting point of 327°C, lead turns into a gas at 1740°C. Another notable example is mercury, which...
