The water gradually dissociates the copper sulfate, and copper ions in solution are blue.
The anhydrous copper(II) sulfate is white, the pentahydrate is blue.
The spreading of blue colour of coppersulphate crystals in water is due to movement of water paticles as well as coppersulphate particles.due to the movement of particles the coppersulphate crystals and water particles mix with each other this is called diffusion.diffusion takes place untill the whole water obtain blue colour.
Water can be condensed on the bottom of the glass cover.
It is important to let the sand settle at the bottom of your beaker so that the sand is separated from the liquid.
to get an accurate reading of the liquid inside the beaker, the thermometer should not rest on the bottom of the beaker.
Luminous flame produce deposit on the bottom of the beaker because when the beaker is near the flame, it limits the amount of oxygen for the methane, thus, the deposit (which is Carbon), is produced.
Put a glass tube into the beaker of water so that it touches the bottom, then drop the crystal down the tube and put your finger over the top of the, then remove the tube gently, leaving the crystal behind in the beaker. After that laugh maniacally at the test tube and you might become an evil genius! Hope this helps! :)

The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
The mass of undissolved potassium nitrate is cca. 3 g.

Decreases!

Inform their teacher and then throw the beaker in the broken glass
hotter
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
