why not all energy transfers result in a phase change

Some substances, such as oxygen, hydrogen, and methane have such a weak attraction level that it makes it very hard to condense due to the amount of energy that needs to be taken away.

Why does an energy transfer not result in phase change?

An energy transfer not result in phase change because you have to add or remove a certain amount of energy to start an type of phase change for example if I removed a degree from a bottle of water it would not freeze or change.

Because energy all substances have a set temperature that when reached, it phase changes. It is also because of the weak attraction level that can make it hard to phase change. For example, water needs to heat up for a long time before it begins phase changing into water vapor.

Phase change does not always happen because some substances need a different amount of energy to change phase, for example lets say water needs 212 degrees to boil into a gas methane might need more or less energy to evaporate.

An energy transfer doesn't always result in a phase change because there is a certain amount of energy required to result in a phase change.

An energy transfer doesn't always result in a phase change as there has to be a certain level of kinetic energy/attraction in a substance for a phase change to occur. Which is different for all substances. Kinetic energy and attraction are always in a tug of war game. An increase in kinetic energy can overcome the pull of attraction, thus separating the molecules, and vice versa. Thus why not all energy transfers lead to a phase change.

An energy transfer doesn't always result in a phase change because if the attraction levels are low, like oxygen, a lot of energy has to be transferred out to change phases.

Energy transfer does not always result in a phase change because some substances require more or less kinetic energy than others. When a substance's molecules reach that level of energy, either the attraction overcomes the kinetic energy, or the kinetic energy overcoming the attraction. A phase change occurs.

Why does an energy transfer not always result in a phase change?

Since sometimes you need a lot more or less energy to have phase change and there is a certain amount or energy you need to result in a phase change for each substance.

Why does an energy transfer not result in a phase change?

2025-09-16 13:56:46 UTC

Because every substance has a different level of attraction so we might need to add or remove more kinetic energy than others so that they will evaporate or condense but because of that each substance will need a different temperature to change in phase

An energy transfer does not always cause a phase because different substances have different levels of attraction in their molecules, like how water vapor condense with a smaller change in temperature, but oxygen had to be cooled to an extremely low temperature in order to condense.

Not all energy transfers will result in a phase change because some substances need a really big amount of energy needed to put in or take out. For example, Oxygen, Hydrogen, Methane is very hard to change from a gas to liquid compared to water vapor because the monocules have a smaller attraction and need extreamly low temps to change to a liquid.

Why does an energy transfer not always result in a phase change?

2025-09-16 13:57:56 UTC

Because the attraction could be weak, like it is for hydrogen and methane, so it won't condense because they first have to reach extremely cold temperatures before condensing because of the attraction between the molecules.

Why doesn't every energy transfer result in a phase change?

2025-09-16 13:58:12 UTC

An energy transfer does not always result in a phase change because in order for a substance to change phase, either molecular attraction or kinetic energy needs to win the tug-of-war battle. Since molecular attraction is always the same, the kinetic energy must change to win the tug-of-war and create a phase change.

Why not every energy transfers result in a phase change

Not every energy transfers result with a phase change because all substances have different attraction levels which means different substances need more or less energy to change phase than other substances.

Because ever substance have a different molecule attraction level and for a phase change to happen it is when either the molecules attraction or kinetic energy is larger. But also for some substances like oxygen,hydrogen, and methane have weak attraction so it is also about how much energy is being transferred in.

An energy transfer does not always result in a phase change because substances need to have a certain amount of energy transfered in or out in order to change phases (depending on the level of attraction for the substance). In the text it states that hydrogen and methane have a very weak attraction, so they need a lot of energy transfered out to become a liquid. Just a little bit of energy transfered out will not cause them to change phases, instead they need to reach extremely cold temperatures in order to change to a liquid. Another example: if you put 4 ice cubes into a cup of water, they will not cause it to freeze/change phase.

An energy transfer does not always result in a phase change because some substances react differently to energy changes. an example of this would be the liquid point of different metals. Most metals have a super high point to when they become a liquid, whereas some metals like mercury and gallium are liquids at room temperature. In conclusion, all substances react differently to different levels of energy, which is why an energy transfer does not always result in a phase change

Energy transfer does not always result in a phase change because some substances need different amounts of energy to change phase than others. This is because some substances' molecules' level is very low, or very high which makes it need a certain amount of energy to change phase.
