1. Some potassium permanganate crystals were added in two beakers A and B containing equal amount of water. Beaker A contains cold water while B has warm water. In which case diffusion will be faster and why?
2. Ice, steam and water are 3 states of a substance and not different substances. Justify.
3. Arrange the following in decreasing order of rate of diffusion in water :
• oxygen
• salt
• ink
4. Melting of a solid requires heat energy but temperature remains constant during the process. Explain.
● Expecting good answers from stars/benefactors/moderators/serious users.

1 diffusion in beamer A will fast cause warm water helps something to diffuse.
2 cause they r constituents of water only
3 oxygen
gas
salt
4 heating of something (object) is not everytime needed...so..... temperature remains contant or u can say in easy kanguage that is AS IT IS.

Annabelle1056:
no 3 reason?
means each point has to be 3 reasons?
nope, what is the reason for question number 3?
yaa i tell u here only....wait..
that is i have arranged it in decreasing order...

howdy dude !!
your answer is --
1) Diffusion occur faster in warm container ( B ) because warm water have more space and kinetic energy than cold water so, potassium permanganate diffuse more fast in container B than A .
2) In ice the molecules are densely packed , in water molecules are loosely packed while in steam the space between their molecules have very high than ice and water but all these three state are the same substance , all three state show same properties .
3). decreasing order is --
• Oxygen( molecules are very far together )
• ink ( molecules are far together but closer than oxygen)
• salt ( molecules are very close together )
4) Melting of a solid requires heat energy but temperature remains constant during the process because on heating solid , energy is absorbed by its molecules in form of heat and increase kinetic energy . so, temperature remain constant .[ this heat is also called latent]
hope it help you
