Does physical change occur when energy is added or removed?
Physical change can occur when energy is added or removed. For example, adding heat energy can cause water to change from a solid to a liquid (melting), while removing heat energy can cause water to change from a liquid to a solid (freezing). These changes do not alter the chemical composition of the substance.
Is thermal energy removed or added in precipitation?
Thermal energy is neither removed nor added in the process of precipitation. Precipitation occurs when water vapor in the atmosphere condenses into liquid water or ice crystals, releasing latent heat in the process. This latent heat is a result of the phase change from vapor to liquid or solid, not a transfer of thermal energy.
What happens if energy is added or removed from a glass of ice water?
If energy is added to a glass of ice water, the ice will absorb the energy and begin to melt. If energy is removed, the ice will give off heat to its surroundings and may freeze further. Ultimately, the temperature of the glass of ice water will change based on whether energy is added or removed.
How much heat must be removed from steam to change it to a liquid?
The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.
Do molecules gain or lose energy from evaporation?
Water molecules gain energy in order to vaporize. That additional energy is needed in order for the water molecules to overcome the attraction that they have for the other water molecules in the liquid that they are part of. In the gas phase, water molecules move independently of each other and are not connected as they are in the liquid state.
What happenes to water vapor when thermal energy is removed?
When thermal energy is removed from water vapor, it cools down and condenses into liquid water. This process of condensation is the opposite of evaporation, where liquid water turns into water vapor when heated.

What might happen if enough energy is absorbed by liquid water?
If enough energy is absorbed by liquid water, it will eventually reach its boiling point and start evaporating into steam. This process is known as boiling and the water will undergo a phase change from liquid to gas.

What state of matter changes state?
a solid → a liquid = melting (heat energy added) e.g. ice melts to water a liquid → a gas = vaporization (heat energy added) e.g. water to water vapour a solid → a gas = sublimation (heat energy added) e.g. dry ice (frozen CO2) to carbon dioxide a gas → a liquid = condensation (heat energy removed) e.g. cloud to rain a liquid → a solid = freezing (heat energy removed) e.g. water freezes to ice a gas → a solid = deposition (heat energy removed) e.g. water vapour to frost * solid-molecules tightly packed definite shape and volume(crystaline structure) * liquid-flow takes shape of container * gas-expands to fill container * plasma-electrons at 5000*C(neon lightning)

When water changes from a solid to a liquid energy is?
Energy is used when water changes from a solid to a liquid.

In the gas phase, water molecules move independently of each other and are not connected as they are in the liquid state.
What change of state happens when heat is removed from water and it condenses?
When heat is removed from water, it undergoes a change of state from a gas (water vapor) to a liquid (water). This process is known as condensation.
