In the same class two students find that a piece of wood with a mass of 70g has a volume of 103 cm3 they conclude the wood is oak is this accurate

The density of oak is ranging from 0.6 - 0.9 g/cm³ and the density of given wood is 0.68 g/cm³ . The piece of wood is oak.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Volume=  103 cm³

Mass = 70 g

Density = ?

Solution:

d = m/v

d = 70 g/ 103 cm³

d = 0.68 g/cm³

The density of oak is ranging from 0.6 - 0.9 g/cm³. so the piece of wood is oak.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
