Answer:

The energy changes form

Explanation:

As the Law of Conservation of energy states, energy can neither be crated nor destroyed. But, it can change form, whether that change is potential to kinetic or energy into heat or entropy, which is to us unusable as it is the energy of disorder.

At which temperature is water in its gas phase (water vapor)?
tankabanditka [31]
Answer: (Assuming we’re going by degrees Fahrenheit) I’d say 140.

Explanation: -40 would be beyond freezing point for water which is 32 degrees Fahrenheit and 40 would nearly be freezing point. For water to transform into its gas phase, the temperature would need to be greater. Therefore, 140 degrees Fahrenheit makes the most sense.

Although I did search it up and 212 degrees Fahrenheit (100 degrees Celsius) is the proven temperature at which water transforms into water vapor so... not sure if there’s more to the question or I’m interpreting the question wrong.

A classroom has a volume of 288m3 .<br><br> What is its volume in km3
katrin2010 [14]
The conversion factor between the unit in meter and that of kilometer is that,                             1 kilometer = 1000m
For the given above,
              (288 m³) x (1 km / 1000 m)³ = 2.88 x 10^-7
Thus, 288 m³ is also equal to 2.88 x 10^-7 km³.

What is the electron configuration of a ground-state cr atom? 1s22s22p63s23p64s14d5 1s22s22p63s23p64s23d4 1s22s22p63s23p63d6 1s2

The electronic configuration of a ground-state Cr-atom :

1s²2s²2p⁶3s²3p⁶4s²3d⁴

<h3><u>What are electronic configurations?</u></h3>

The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.

According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.
