The three changes of state during which energy is absorbed are:

1. Change from solid to liquid - Melting.

2. Change from liquid to gas - Vaporization

3. Change from solid to gas - Sublimation

All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.

Three changes of state during which energy is absorbed are : 1. solid to liquid - heat goes into the solid as it melts. 2. Liquid to gas - Heat goes into the liquid as it vaporizes. This change of state includes boiling and evaporation. 3.Solid to gas - this is sublimation. Heat goes into the solid as it sublimates. Change in phase of a material or substance always involves a change of heat whereby heat energy is either absorbed into the material or given up from the material

The orbital cavities , nasal cavity, paranasal sinuses, and the oral cavity are all located in what region of the body
trasher [3.6K]

These are all part of the head or skull. The cavities of the skull surround and protect the brain and sensory organs. There are five kinds of cavities of the skull which are:


nasal cavity (paranasal sinuses is included here) - The nasal septum split the respiratory system into two lateral halves, the nasal cavity is also part of the respiratory system.


<span>cranial cavity - The large cranial cavity is split into a posterior cranial fossa and an anterior cranial fossa, a middle cranial fossa. Its function is to support the brain.</span>

<span>
</span>

oral cavity - The oral, or buccal, cavity (commonly called the mouth) is a cavity of the head rather than a cavity of the skull because of its fleshy and muscular floor.


orbital cavity - supports and defends an eyeball and its linked muscle, vessels, and nerves.


<span>middle ear cavity - From outer to inner, three small bones-malleus, incus, and stapes are situated within the middle-ear cavities in the petrous part of the temporal bones.</span>

Answer:

As one goes up the other does as well for the first 2 but they aren't proportional (it is not simple cause and effect as there is a lot of factors)

The last question is to decrease their emissions as rising temperature is being effected by rising CO2 levels and rising temperature can cause a feedback loop causing more rising temperature
