decrease in temperature and compact arrangement of its atoms..in the state of ice the water has the least density i-e 0.9168 g/cm3.
Freezing is the change in state from liquid to solid.
The change in state from a solid to a liquid is called melting.
A physical change from solid to liquid state is caused by an increase in temperature, which provides enough energy to overcome the forces holding the solid particles together. This causes the solid particles to gain enough kinetic energy to break free from their fixed positions and move more freely, resulting in the transition to a liquid state.
A change in state can be caused by either adding or removing energy from a substance. For example, adding heat can cause a solid to melt into a liquid, and removing heat can cause a liquid to freeze into a solid. Pressure changes can also cause a substance to change state, such as turning a gas into a liquid by increasing pressure.
The state of liquid to Solid is ; Freezing
The state of liquid to Solid is ; Freezing
The change of state from solid to liquid is called melting.
The change in state from solid to liquid is called melting.
a phase change: solid to liquid: melting liquid to solid: freezing liquid to gas: vaporization gas to liquid: condensation solid to gas: sublimation gas to solid: deposition
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
In a word, temperature. A physical change will change the matter's state based on it's temperature. For example, water, H2O. You can increase the temperature to 212oF and it will change state from a liquid to a gas. You can decrease the temperature to 32oF and it will change state from a liquid to a solid. To answer your question, the process of doing so would be increasing or decreasing temperature of matter.
To change from a solid to a liquid, heat the substance until it reaches its melting point. The increase in temperature causes the solid's particles to gain enough energy to break free from their fixed positions, resulting in the solid turning into a liquid state.
