why is energy required for the boiling process

Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.

Heating Curves

In Figure 10.18, the solid gains kinetic energy and consequently rises in temperature as heat is added. At the melting point, the heat added is used to break the attractive intermolecular forces of the solid instead of increasing kinetic energy, and therefore the temperature remains constant.

Does it require more energy to vaporize water at the boiling point or to melt water at the melting point explain?

6. Does it require more energy to “vaporize” water at the boiling point or to melt water at the melting point? Explain. It takes more energy to vaporize than to melt because the horizontal section of the graph is much longer during the vaporizing, or boiling.

Why does melting ice require much less energy than boiling the same mass of water?

For example, when heat energy is added to ice at its melting point ( A solid substance at its melting point has less energy than the same mass of the substance when it is a liquid at the same temperature. … This heat energy allows the change of state to happen, and the temperature remains constant during the process.

Does evaporation require more energy than melting?

The energy gained during vaporization requires 2260 Joules/gram, while the energy gained during melting is only 334 Joules/gram.

Why does it take more heat to vaporize water?

It takes a lot of heat to increase the temperature of liquid water because some of the heat must be used to break hydrogen bonds between the molecules.

Is energy released or required for evaporation?

Energy is required to change from solid to liquid, liquid to gas (evaporation), or solid to gas (sublimation). Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid. … Evaporation is a cooling process.

Can you explain why you think it takes more energy to change water from liquid to gas versus solid to liquid?

Gaseous water contains more energy than liquid water due to the energy needed to change its state of matter because you first have to boil the water and then change it to steam. Steam burns are more severe than liquid water burns! When a liquid turns into a gas, we call this process evaporation.

Why does a substance need a lot of energy to change state?

This is because matter is affected by energy. If a substance absorbs enough energy, atoms, and molecules move around more. The increased kinetic energy can push particles far enough apart that they change form.

Why does it take more energy to go from liquid to gas?

The enthalpy of vaporization of a given substance is much greater than its enthalpy of fusion because it takes more energy to completely separate molecules (conversion from a liquid to a gas) than to enable them only to move past one another freely (conversion from a solid to a liquid).

Does melting gain or lose energy?

Melting is the change of state from a solid to a liquid. B. Adding Energy: When a solid is at its melting point, any energy added to it is used to overcome the attractions that hold the particles in place.
