When a sample of liquid is cooled then what happens to the thermal energy?
When a sample of liquid is cooled, its thermal energy decreases as the molecules lose kinetic energy and move more slowly. This reduction in thermal energy can lead to a decrease in temperature and may eventually cause the liquid to solidify if cooled sufficiently. The lost thermal energy is typically transferred to the surrounding environment.
How can a matter change from solid state to liquid state and reverse the process?
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.
When liquid gold becomes a solid?
Since its melting point is 1064.18 degrees Celsius - it will solidify at any temperature below that !
What does an increase of temperature do to the KE of a liquid?
An increase in temperature of a liquid causes the kinetic energy (KE) of the liquid molecules to increase. This increase in thermal energy leads to faster movement of the molecules, resulting in higher kinetic energy.
What is the temperature at which a liquid changes to a solid called is there a gain or a loss of energy?
Such a temperature is known as Freezing point of the liquid, during the freezing process the system losses the energy.
What happens if you remove thermal energy from a liquid?
If thermal energy is removed from a liquid, its temperature will decrease, causing it to eventually solidify if enough thermal energy is removed. The speed at which this occurs depends on the specific properties of the liquid.
Why does a liquid solidify when you cool it?
When a liquid is cooled, its particles lose energy and slow down, causing them to come closer together and form a more ordered arrangement. This process is known as freezing or solidification, leading the liquid to solidify into a solid state.
Do you add more energy when you freeze liquid?
No, freezing liquid actually removes energy from it in order to lower its temperature and solidify it. When a liquid freezes, the molecules slow down and come together to form a solid structure, releasing heat in the process.

What is needed in order far liquids to solidify?
For liquids to solidify, the temperature of the liquid must be below its freezing point. Every substance has a different freezing point. For example, water's freezing point is 0 degrees Celsius. At 1 degree, it will be a liquid. If you cool it down to -1, it will solidify.
What happens if energy is added to a liquid at 20 Celsius?
If energy is added to a liquid at 20 Celsius, the temperature of the liquid will increase. This can lead to a phase change if the added energy is sufficient to raise the liquid's temperature above its boiling point, causing it to vaporize. If the added energy is not enough for a phase change, the increased temperature can affect the liquid's properties such as viscosity.
A container of melted paraffin wax is allowed to stand at room temperature until the was solidifies what is the direction of heat flow as the liquid wax solidifies?
To solidify, the paraffin has to get rid of excess heat, so the heat flow is outward.
When a liquid is cooled the molecules in that liquid?
I assume you mean what happens to the molecules... They slow down due to the loss of kinetic energy when the liquid is cooled. When they are sufficiently cooled as to cause freezing, that's a different story.
When liquid gold becomes a solid?
Since its melting point is 1064.18 degrees Celsius - it will solidify at any temperature below that !
