If energy is removed from liquid water, it would cool down and eventually freeze into solid ice at its freezing point (0 degrees Celsius or 32 degrees Fahrenheit).
When energy is removed, the decrease in energy causes the particles to slow down or cool down. This can lead to a decrease in movement and a potential change in state, such as from gas to liquid or solid.
To decrease the thermal energy of a metal block, you can cool it down by placing it in a colder environment or by using a cooling agent such as ice or liquid nitrogen. Increasing the surface area of the block can also help to speed up the cooling process.
If energy is removed from a solid, the particles that make up the solid will lose kinetic energy and slow down. This will result in a decrease in temperature, causing the solid to cool down until it reaches thermal equilibrium with its surroundings.
When thermal energy is removed from matter, its temperature decreases. This is because temperature is a measure of the average kinetic energy of particles in a substance, so removing thermal energy reduces the kinetic energy and hence the temperature.
If energy is removed from liquid water, it would cool down and eventually freeze into solid ice at its freezing point (0 degrees Celsius or 32 degrees Fahrenheit).
It is 15188 Joules.

You can decrease the thermal energy of a metal block by allowing it to cool in a cooler environment, such as placing it in contact with a cooler surface or exposing it to a colder surrounding. Alternatively, you can reduce its thermal energy by transferring heat away from the metal block through a process like conduction or convection.
To freeze liquid water at 0 degrees Celsius, you need to remove 334 J/g of energy. To cool it from 0 degrees Celsius to -20 degrees Celsius, you need to remove an additional 80 J/g. Therefore, for 75g of water, the total energy released would be 75g * (334 J/g + 80 J/g) = 33,200 J.
The output energy of a fridge is typically in the form of heat released into the surrounding environment. This heat is removed from the interior of the fridge to keep the contents cool. The energy output is mainly in the form of thermal energy.
If thermal energy is removed from a liquid, its temperature will decrease, causing it to cool down. Eventually, if enough energy is removed, the liquid can reach its freezing point and turn into a solid. The process of removing thermal energy from a liquid is known as cooling or chilling.
If you remove heat from water, it will cool down and eventually freeze into ice at 0 degrees Celsius. The water molecules will slow down and lose energy as heat is removed, causing them to come together more closely and form a solid structure.
When thermal energy is removed from a substance, the molecules lose kinetic energy and slow down. This often causes the substance to cool down as the molecules have less energy to move and vibrate. In extreme cases, the substance may undergo a phase change, such as from a liquid to a solid.
