When a surface water molecule gains enough energy to break free from the bond it has with other water molecules around it, it moves upward and mixes with air. The single water molecule has more energy, moves independently and is a gas. Vaporization at boiling point is called boiling.

Thermal Energy is a form of Kinetic Energy because it is related to the Molecular Velocity. When liquid water is heated its temperature may rise or it may turn to Water Vapor/Steam. When liquid water turns to steam the molecules move (faster or slower) and heat is (added or removed) from the water.

Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called evaporation. Snow and ice can also become water vapor through a process called sublimation.

The water particles in each state behave as energy is absorbed or released. . Condensation, deposition, and freezing are processes that occur as a result of a decrease in the heat energy of water particles. When solid ice gains heat, it changes state from solid ice to liquid water in a process called melting.

Because of kinetic energy water can flow and waves can exist. But water can also contain potential energy. This is energy that is stored in the water.

The answer is that it takes a lot of energy to convert water from a liquid state to a gaseous state. As the sweat on your skin vaporizes into the air, it steals heat energy as it disappears. The answer is that the evaporation of water from your skin lowers the temperature of the water that is left behind.

The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together.

Note that melting and vaporization are endothermic processes in that they absorb or require energy, while freezing and condensation are exothermic process as they release energy.

Freezing happens when the molecules of a liquid get so cold that they slow down enough to hook onto each other, forming a solid crystal. For pure water, this happens at 32 degrees Fahrenheit, and unlike most other solids, ice expands and is actually less dense than water. That is why ice cubes float!

An input of 334,000 joules (J) of energy is needed to change 1 kg of ice into 1 kg of water at its melting point of 0°C. The same amount of energy needs to be taken out of the liquid to freeze it.

The amount of heat released when the water freezes is also known as the latent heat of fusion and is equal to 80 calories per gram of water or, 334 Joules per gram of water.

A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting. At 0°C, liquid water has 334 J g−1 more energy than ice at the same temperature. This energy is released when the liquid water subsequently freezes, and it is called the latent heat of fusion.

– To melt 1 gram of ice requires 80 calories. (A calorie is defined as the amount of energy needed to raise one gram of water 1°C.) – The change from liquid to ice is called solidification.

At temperatures below 32°F (0°C), liquid water freezes; 32°F (0°C) is the freezing point of water. At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point.

The molecules of water have more energy than the molecules of ice at the same temperature, this is because as ice is melted to the liquid state, ice absorbed energy which is used in breaking the inter particles forces between the ice and hence water molecule have more kinetic energy.

gas

Answer: C steam has the maximum energy.

kinetic energy

Ice cubes are placed on metal and plastic blocks; the cube placed on metal melts much more quickly than the cube placed on plastic.

The molecules in the soft drink move faster than the water molecules in the ice cubes because they are at a higher temperature and, therefore, have a higher average kinetic energy than the water molecules.

Why did the ice cube melt quicker on the metal surface than on the wooden surface? Even though the metal block feels colder than the wooden block, it transfers the heat it has to the ice cube more easily than the wooden block does, and this makes the ice cube melt faster.

A standard 1 ounce cube (30 grams) will take 90 to 120 minutes to melt at the same temperature.

Water that is under the ice and that has a temperature above the freezing point causes the bottom surface of the ice to melt. Warm surface waters cause the edges of the ice to melt, particularly in leads and polynyas.

General insulation of the ice causes it to melt slower. Wrapping it in wool, Styrofoam or wood contains the cold air emitting from the ice, keeping the temperature of the ice low. If no air is moving around the ice, it cannot warm with the atmosphere and melt faster.
