Explanation:

Density is defined as the degree of compactness or mass per unit volume.

Mathematically,         density = \frac{mass}{volume}

It can be seen from the formula that mass is proportional to density. That is, more is the mass of an object more will be its density.

Therefore, it is given that iron nail sinks to the bottom this means that the iron nail has highest density as compared to the piece of wood and a styrofoam cup.

Thus, we can conclude that given experiment demonstrates the density of given objects.

the density of pure gold (au) is 19.3 g/cm3. what is the mass of a block of gold that measures 1.2 cm x 5.00 cm x 3.20 cm? pleas
Julli [10]

The density of pure gold (au) is 19.3 g/cm3. what is the mass of a block of gold that measures 1.2 cm x 5.00 cm x 3.20 cm? please show work.


Given: Density of pure gold = 19.3 g /cm^3

Measurement of block of gold =1.2 cm x 5.00 cm x 3.20 cm

To calculate : mass of gold

Formula used: Density = Mass / Volume

Volume = 1.2 cm x 5.00 cm x 3.20 cm = 19.2 cm^3

Mass of gold = Density X volume = 19.3 g /cm^3 X 19.2 cm^3  = 370.56 g

Please help with question 4 and 5 please!!
ratelena [41]
Question four is : Gaseous state

Question five is : A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.

Hope this helps!

Have a great day!
