if you know how fast it was when it hit the surface of the water, you can calculated how the object is going to move inside water provided you are given extra information, namely the "viscosity" of water in the beaker. The viscosity is the measure of the resistance of the liquid for objects moving inside it, and it is temperature dependent. Once you have the viscosity of the water it becomes very easy calculation.
i think the lowest density.
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
Water can be condensed on the bottom of the glass cover.
Decreases!
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.
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.
The bottom and sides of the beaker will be hotter than the liquid inside.
They will diffuse equally throughout the beaker
