To melt ice you must supply the latent heat which is a fixed amount per unit weight.

What happens to the molecules in a substance when thermal energy is removed?
It's vibrates and then melts
How does the speed of the molecules change when ice changes to water?
Their speed - Kinetic Energy - increases as the solid melts.
What happens to the arrangement of water molecules as water melts and freezes?
When water freezes the molecules come together and become more orderly. When water melts the molecules loosen apart.
Why does stearic acid melt at 69 but linoleic acid melts at9?
Linoleic acid is an unsaturated fatty acid. This means less energy is required to separate the molecules due to its irregular/bent shape. The bends come from the cis double bonds in the carbon chain.
Why does salt temp stay same temp when it melts?
The total kinetic energy of molecules must remain constant during changes of phase.
What happen to the arrangement of water molecules as ice melts?
The arrangement of water molecules start having their chemical bonds break as ice melts. Hydrogen bonds constantly form and break constantly moving everything out of position.
What happens to water molecules as ice melts in terms of kinetic molecular thery?
As the ice melts, the water molecules gain energy, causing them to move more quickly.
What happens to the molecules in a substance when thermal energy is removed?

Do molecules gain or lose energy from melting?
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
What happens to energy when ice melts to form liquid water?
The ice needs to absorb heat energy in order to melt. This energy is stored in the water as a type of potential energy (it requires a force, and therefore energy, to separate the water molecules). When the water freezes, this potential energy is returned once again.
Describe the role of energy when ice melts and when vapor condences to form liquid water?
When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
Is energy absorbed or released when a solid melts a liquid vaporizes a gas condenses and a liquid melts?
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
How does the speed of molecules change when ice change to water?
Their speed - Kinetic Energy - increases as the solid melts.
How does the speed of the molecules change when ice changes to water?
Their speed - Kinetic Energy - increases as the solid melts.
What happens to the molecules in a liquid when it melts?
When a solid melts, intermolecular forces that were holding the molecules tightly together are overcome by the kinetic energy introduced by heating the substance. All of the molecules are still present; they are just more widely dispersed and can move more freely, causing the fluid properties of liquids.
What happens on a molcular level when a substance melts?
Its molecules starts vibrating more than when they were solid. Their kinetic energy are greater.
How the energy of matter changes when it melts.?
When a solid melts, it is due to an increase in thermal energy to the temperature at which it melts.
