Gas to liquid.
During a change of state, such as melting or boiling, the temperature generally remains constant. The energy added or removed during the phase change is used to break or form intermolecular forces, rather than changing the kinetic energy of the particles to alter temperature. Once the change of state is complete, the temperature will then either increase or decrease again depending on whether heat is added or removed.
When a gas condenses, it changes from a gaseous state to a liquid state as its particles come closer together due to a decrease in temperature or an increase in pressure. This process releases energy in the form of heat.
When water vapor condenses, it changes from a gaseous state to a liquid state. This process releases energy in the form of heat. The water molecules come together and form liquid droplets, which can be seen as clouds in the atmosphere or as dew on surfaces.
When water vapor loses heat, it condenses back into liquid water. This process is known as condensation. It occurs when the temperature of the air is lowered, causing the water vapor to change state from gas to liquid.
When water vapor condenses to form a liquid, the average speed of the water molecules decreases. This is because the molecules are moving closer together and are held more tightly by intermolecular forces in the liquid state.
This is a gas.
A change of state is when a substance shifts from solid, liquid or gas to another state. This happens when heat is removed or added.
Changes in the state of matter occur when the amount of heat energy is changed in a substance. When it is removed, gas condenses and liquid freezes. When it is added, solids melt and liquids boil.
Condensation is a physical change, as the chemical identity of the substance is not altered by condensation.
This is a physical change. When water vapor in the air condenses to form clouds, it is a change in state from a gas (water vapor) to a liquid (water droplets). No new substances are formed.
The change is from gas to liquid: H2O in the gaseous form condenses into the liquid we know as water.
During a change of state, such as melting or boiling, the temperature generally remains constant. The energy added or removed during the phase change is used to break or form intermolecular forces, rather than changing the kinetic energy of the particles to alter temperature. Once the change of state is complete, the temperature will then either increase or decrease again depending on whether heat is added or removed.
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
When a gas condenses, it changes from a gaseous state to a liquid state as its particles come closer together due to a decrease in temperature or an increase in pressure. This process releases energy in the form of heat.
When water vapor condenses, it changes from a gaseous state to a liquid state. This process releases energy in the form of heat. The water molecules come together and form liquid droplets, which can be seen as clouds in the atmosphere or as dew on surfaces.
A change in the state of matter occurs when heat energy is added or removed.
When water vapor condenses into liquid water, it changes from a gas to a liquid state due to a decrease in temperature. This process releases energy in the form of heat, known as the latent heat of condensation. Condensation is responsible for the formation of clouds and precipitation in the atmosphere.
