Because the molecules vibrate and then bounce off off each other causeing them to spread apart.
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
When a solid turns to a liquid, such as ice turning to water, it is commonly called melting. The solidification of a liquid to a solid is called freezing.
liquid to solid
It is called melting when a solid turns into a liquid
A liquid changes into a solid state when its particles start losing energy. This is usually due to a decrease in temperature because if there is less heat energy present, there is less kinetic energy produced in the particles. As the particles of the liquid continue to slow down its vibration speed, it becomes a solid. The word for this is known as freezing and the best example for it is the change of state from water (liquid) to ice (solid).
Let's consider the case of ice. Ice is a solid. When heated, it gets transformed to water. Water is a liquid. Further heating changes water into gas. Thus, heat can change a solid into both liquid and solid form.
A liquid is like a solid because a liquid I usually a heated solid Ex. Water is heated ice
Ice melts into water, wax melts into liquid, and metal expands when heated.
Ice (solid water) changes to liquid water when heated. Wax solid changes to liquid wax when heated. Metal becomes molten when heated to its melting point. Paraffin wax solid changes to liquid paraffin wax when heated.
Water changes state depending on its temperature and pressure. When water is heated, it can change from a solid (ice) to a liquid (water) to a gas (steam). When water is cooled, it can go from a gas to a liquid to a solid. These changes in state are due to the energy levels of the water molecules.
Heat can cause a change in the state of matter, such as from solid to liquid (melting) or from liquid to gas (evaporation). The materials involved in these changes can vary depending on the specific substance being heated. For example, water changes from ice to liquid water when heated, while dry ice (solid carbon dioxide) changes directly into carbon dioxide gas when heated.
Four examples of changes in state are: solid to gas (sublimation), gas to solid (deposition), solid to liquid (fusion), and gas to liquid (condensation).Four examples of change on state are liquid to solid, solid to liquid, liquid to a gas, and gas to a liquid.
The four-letter word you are looking for is "melt." It describes the process of a solid turning into a liquid as it is heated, such as ice melting into water.
When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
What type of change occurs when water changes from a solid to a liquid
The phase of water changes in response to temperature and pressure. When water is heated, it changes from a solid (ice) to a liquid (water) at its melting point, and then to a gas (steam) at its boiling point. Conversely, when water cools down, it transitions from a gas to a liquid to a solid.
In the case of water (liquid) you would freeze it into ice (solid).
