Answer 1

Hello Mate!

1. Nepthalen balls disappear with time without leaving any solid because nepthalene valls sublime to directly change into the gasous state with changing into liquid state.

2. Steam produces more severe burns because it onsist of latent heat ( hidden heat ) where as there is not latent heat in boiling water.

3. Ink will sure spread faster because it small particles will diffuse faster in water where as honey's particle will take some more time to diffuse completely
