formula for density

D=m/v

why would a marble sink and a glass Of water

Marbles densities more than the water

Why is density important part of matter?

so we can identify substances and help us understand if the object were float or sink

solute definition

what is being dissolved for example Kool-Aid

Solvent definition

concentration define

Measure the amount of solute in a given amount of solution

What is the solvent in the solute for sugar dissolving in water?

The solvent is water in the solute is sugar

Independent variable

variable that is changing

depend Variable

Variable that is affected by the change, for example, what is being measured

quantitative data

Has to do with numbers, for example, in trial one the car went 70 mph

What are the units we used to measure a graduate cylinder length and mass

Grams, centimeters inches feet in grams/milliliters

Why is it important to be able to separate Mixtures

To remove tops, toxic substances, for example, salt from drinking water

process of distillation

yeah, purifying a liquid by a process of heating and cooling

how to find the volume of an irregular object

V=m/d

What holds atoms together in a molecule?
