Answer:
Volume
Explanation:
Density:
Density is equal to the mass of substance divided by its volume. In order to find the density of earth when mass is given we have to calculate its volume. The volume of earth is calculated by using the volume formula for sphere. i.e 4/3 π r³. we also require radius to find the volume and we know that
Diameter = 2 × radius
The diameter of earth equator is 12756.75 Km. So we calculate the radius by dividing the diameter by 2. Then by putting the value of radius in 4/3 π r³ we will get the volume and then we can calculate the density of earth.
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.
Answer:Typical physical properties of metals : high melting points. good conductors of electricity. good conductors of heat.
Explanation:
Hello:
In this case, we will use the Clapeyron equation:
P = ?
n = 8 moles
T = 250 K
R = 0.082 atm.L/mol.K
V = 6 L
Therefore:
P * V = n * R * T
P * 6 = 8 * 0.082* 250
P* 6 = 164
P = 164 / 6
P = 27.33 atm
Hope that helps!
Answer:one gram by 1oC
Explanation: you will need to know the value of water's specific heat
Answer:
a) 
b) 
c) 
Explanation:
Hello,
a) In this case, the given height in cm is:
And the radius in cm is:
Thus, the volume in cubic centimeters which is also equal in mL (1cm³=mL) is:
b) In this case, the given height in mm is:
And the radius in mm is:
Thus, the volume in cubic millimeters is:
c) Finally, since 1000 mL equal 1 L, the required density in g/L turns out:
Best regards.
