Water has hydrogen bonds between Hydrogen atoms (that are slightly positive in molecules of water ) and Oxygen atoms (that are slightly negative in molecules of water), so it is necessary more energy to break them down and move water molecules from liquid state to gas.
(V1/T1)=(V2/T2) this is Charles' law where T is in Kelvin
So: (1.53x10^3)/(275K) = V2/(372K)
V2= 2.07x10^3L
Answer:
An emulsion is a type of colloid formed by combining two liquids that normally don't mix.In an emulsion,one liquid contains a dispersion of the other liquid.Common examples of emulsion include egg yolk,butter etc.The process of mixing liquids to form an emulsion is called emulsification.
Answer:
Wasim and Nehra did the Proper testing
Explanation:
In acidic condition Blue litmus turns red
In basic condition Red litmus turns Blue
In order to test an Acidic solution we need Blue litmus.
Wasim Dipped the blue litmus in the solution : it will turn red and shows acid
Akram Dipped the red litmus in the solution : No it will not show, it's a test for base
Neha: Dipped both the blue and the red litmus in the solution one after other.
Blue litmus will turn red which will show Acidic nature, after that Adding Red litmus in it will not show any change as Red litmus only changes in Basic condition.
Therefore, Wasim and Nehra did the Proper testing
Answer:
Hormones
Explanation:
Hormones are chemical messengers released in one part of the body as chemical messengers into the bloodstream to achieve target results in another part of the body. The endocrine system is responsible for regulation of the internal environment (homeostasis).
