Water has hydrogen bonds that can hold a large amount of heat. These bonds are even stronger in ice. The electrons in the water molecules are slower as there is an absence of energy (heat ). That means that the electrons in the hydrogen will create a small but substantial bond as they loop around, making the already present hydrogen bond stronger. The molecules will become more compact and will result in ice formation. To weaken it, energy (heat) must be added to make these electrons spin faster and create a weaker bond between them. This will result in less compact water molecules (liquid water).

When heat is supplied to a solid substance what happens to the energy?
When heat is supplied to a solid substance, the energy is absorbed by the molecules, causing them to vibrate faster and thus increasing their kinetic energy. This increase in kinetic energy allows the solid to eventually change phase into a liquid or gas, depending on the substance and the amount of heat supplied.
How many photons at 660 nm must be absorbed to melt 5.0 x 10 x10 g of ice?
To calculate the number of photons needed to melt the ice, you would need to determine the energy required to melt the ice and then convert that energy into photons at 660 nm. This involves calculating the energy required to melt the ice using the heat of fusion of ice and then dividing that by the energy of a photon at 660 nm.
How many joules of heat energy must be supplied to 21 g of water to raise the temperature of the water from 24 to 95 degrees Celsius?
The specific heat capacity of water is 4.18 J/g°C. To find the heat energy needed to raise the temperature, you can use the formula: Q = m * c * ΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Plugging in the values, you can calculate the heat energy required.
Does melting lose or gain energy?
Melting gains energy because it requires heat energy to break the intermolecular forces holding together the solid molecules. This energy is needed to overcome the attraction between the molecules and allow them to move more freely as a liquid.
Why is energy needed to melt a solid?
As you heat up a solid, you are adding energy energy to the bonds between the solid molecules to the point that you are breaking these bonds. As you keep adding heat, these bonds become weaker, some break, and eventually the solid molecules can now move a bit more freely about. This is the transformation of a solid to a liquid. Just think of it as the solid molecules becoming more mobile.
When heat is supplied to a solid substance what happens to the energy?
When heat is supplied to a solid substance, the energy is absorbed by the molecules, causing them to vibrate faster and thus increasing their kinetic energy. This increase in kinetic energy allows the solid to eventually change phase into a liquid or gas, depending on the substance and the amount of heat supplied.
The heat of fusion for water is the amount of energy that must be absorbed for water to what?
Melt.
What must be absorbed for a solid to melt?
They must gather close together until they can't bunch anymore and then they start to melt because they ran out of space.
Is heat added or released during freezing?
This is latent heat. When a liquid freezes heat is released, and when it melts the same amount of energy must be supplied. Similarly when a liquid changes to a vapor, or when a vapor condenses, heat must be supplied or is released. Latent heat varies from one substance to another, and can be quantified as so many calories per gram or kilogram, you can find data in reference tables
Which of the changes from a solid to a gas will involve an input of heat energy?
The transition from a solid to a gas involves two steps: first, the solid must melt into a liquid, absorbing heat energy in the process; then, the liquid must vaporize into a gas, which also requires an input of heat energy.
What is heat of fusion of water to melt ice cube?
The heat of fusion of water, which is the amount of heat energy required to melt one gram of ice at its melting point, is approximately 334 joules per gram. This means that to melt an ice cube, the ice must absorb 334 joules of heat energy per gram to transition from a solid to a liquid state.
Why does a desert cooler cool on a hot dry day?
Evaporation requires heat to supply the energy of vaporization. This heat is supplied by the unevaporated water, which must correspondingly cool.
What must be added to a solid to cause it to melt?
Heat must be added to a solid to cause it to melt. As the temperature increases, the solid gains enough energy to overcome the forces holding its particles together, causing them to move more freely and transition into a liquid state.
Why the temperature does not rise during the process of melting and boiling though the heat energy is constantly supplied?
During the process of melting and boiling, the heat energy supplied is being used to break the intermolecular forces holding the substance together. This energy is known as latent heat and does not result in a temperature increase because it is being used to change the state of the substance rather than raise its temperature. Once all the substance has melted or boiled, any additional heat energy supplied will then raise the temperature.
What must occur for a solid to melt?
A solid must absorb enough heat energy to break the intermolecular forces holding its particles together. Once the particles have enough kinetic energy to overcome these forces, they are able to move past each other and the solid transitions into a liquid state through the process of melting.
How much heat energy must be absorbed to completely melt 35 grams of h2o at o degrees?
it will be 11,700J since the formula would be: q=mHf=35g x 334 J/g= 11,700 J
How does solids turn into liqiud?
You must melt the solid with heat
