1) the basic unit of mass (SI unit) is Kg

2) the amount of matter in an object is known as density, infact the amount of matter in a unit volume is density

3) We can measure the mass with a balance

Burette: for volume

rule : for length

graduated cylinder : for volume

4) Weight is measure of force of gravity on a matter

5) the density of water = 1 g / mL at 4 C

so mass of 1 mL of water will be equal to 1 gram

 Consider a bathtub filled with water, with a plug in the drain. How long would this be considered a closed system?
Monica [59]
For a closed system, you need two things:
1) a conservation of mass within the boundaries of the system
2) the ability to freely exchange energy to & from the "closed" system with a surrounding external system


So, the answer is <u><em>never</em></u>, since your defining the "system" as the water within the bathtub, and an open bathtub is exposed to evaporation, which is not conserving mass within the defined "system".
