When a molecule is going through any physical change, solid to liquid or liquid to gas, as it changes, the temperature remains constant. it does not increase or decrease, it stays at that temperature/.
For example, water evaporates/ boils at 100 C. if you are heating water to the point of boiling, it will remain 100 C until all the water evaporates. Once it becomes a gas, the temperature will continue to increase

Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.
Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz. This is due to the inverse relationship between wavelength and frequency which also occurs betwwn wavelength and energy of light rays with the red light having less photon energy of about 1.65–2.00 eV and the blue light with high energy photons of about 2.64–2.75 eV.
Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
Answer:
Structure has been shown below
Explanation:
- In a Lewis structure, least electronegative atom is taken as central atom (except H)
- Total valence electrons of constituting atoms are used to construct Lewis structure
- A bond between two atoms are represented by a horizontal line or a dotted line (two dots).
- Spatial rearrangement of atoms are neglected in Lewis structure.
- H has one valence electron and O has six valence electrons. So, total valence electrons in
are 8 - Lewis structure of
