    Chemistry Density
AI Thread Summary
To calculate the density of a solid, one can measure the dimensions of a regular shape to find volume or submerge an irregular shape in water to determine its volume via displacement. For liquids, density can be calculated by weighing a known volume or using a hydrometer for direct measurement. The formula for density, rho = m/v, is consistently applied in both cases. The discussion highlights the need for clarity in homework questions regarding density calculations. Understanding various methods enhances the ability to accurately determine density for both solids and liquids.

Homework Statement


Give two examples of how you calculate the density of a solid, and two examples of how you calculate the density of a liquid.


Homework Equations


rho=m/v


The Attempt at a Solution


Now, the only way I know to find the density is to find volume, then mass and using rho=m/v. And for the liquid, doing the same thing... So I understand one method of each, but the other method eludes me.

Not a very well written question.
I suppose for the solid you could either measure the sides and calculate the volume for a regular shape or sugmerge it in water for an irregular one.
Density of a liquid you could weigh a volume or use a Hydrometer.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
