Metallic elements can bend because they have the property of being ductile. This means that a solid material stretches under tensile stress. If a material is ductile then it may be stretched into a wire. Further, the material can also be malleable.
True. Its simple how i remeberd was the bone has 650,000 cells and the bone has 65% hydroxyapatite
Answer: The initial volume of the system is 60.29 L.
Explanation:
According to the first law of thermodynamics,
As it is given that heat is being added to the system so, 
will be positive. And, work done on the system is negative and work done by the system is positive.
So here, 
= -107.4 J
Q = 52.7 J
P = 0.693 atm
And, W = PdV
or, W = 
So, 
-107.4 J = 52.7 J - 0.693 \times 101.325 (63.2 - V)
-160.1 = -43.79 - 70.21 (63.2 - V)
63.2 - V = 
- V = 2.90 - 63.2
V = 60.29 L
Thus, we can conclude that the initial volume of the system is 60.29 L.
Answer:
Concentration for the solution is 0.153 mol/L
Explanation:
Formula for the osmotic pressure is π = M . R . T . i
where M is molarity (concentration), R the universal constant for gases and T is Absolute T° (T°C + 273)
π = Osmotic pressure.
Let's replace the data given:
3.9 atm = M . 0.082L.atm/mol.K . 310K
3.9 atm / 0.082 mol.K/L.atm . 310K = 0.153 mol/L (M)
i = Van't Hoff factor (ions from the solute dissolved in solution)
In this case, we assumed no ion pairing, so i = 1
