States of Matter

The iron blade has a ring in which the wooden handle is fixed. The ring is slightly smaller in size than the wooden handle.
The ring is heated and it becomes slightly larger in size (expands). The handle  fits into the ring. When the ring cools it contracts and tightly fits on the handle.

A liquid with low specific heat capacity requires less heat to change its temperature, making it more sensitive to small temperature changes in thermometry.

The freezing point of water at standard atmospheric pressure is 0 degrees Celsius. At this temperature, liquid water transitions into solid ice.

Salt and sugar are soluble in water, meaning they dissolve. Sand is insoluble and will settle at the bottom.

Evaporation is the process by which liquid water turns into water vapor at temperatures below the boiling point. This is how wet clothes dry when exposed to the sun.

Both boiling and evaporation involve a phase change from liquid to gas. Boiling occurs throughout the liquid at a specific temperature, while evaporation occurs at the surface at various temperatures.

Freezing is the process where liquid water loses heat and changes to solid ice at 0°C for pure water. Water gains heat during melting, not freezing. Freezing changes liquid to solid, not solid to liquid.

When warm water vapor comes into contact with a cold surface, it loses heat energy. This causes the gas to transition back into a liquid state, a process known as condensation.

Freezing is an exothermic process (heat loss), and evaporation is a process that requires energy input from the surroundings (heat gain). Since freezing is heat loss, the statement is false.

Melting is the phase transition where a substance changes from a solid state to a liquid state by absorbing heat.

Mist is formed when water vapor in the air cools down and condenses into tiny liquid water droplets suspended in the air.

Condensation is the process where a substance in a gaseous state changes into a liquid state, typically when cooled.

An iceberg is made of solid water (ice). When it melts, it transitions from a solid state to a liquid state.

Boiling is the rapid phase transition from liquid to gas that occurs specifically at the boiling point (100 degrees Celsius for water at sea level).

Thermal expansion is a common property of matter. When heated, particles gain kinetic energy and move further apart, causing the material to expand.
