Answer:
Yes, it's temperature dependent
Explanation:
A good fractional distillation depends largely upon maintaining a temperature gradient within the column. Perfectly, the temperature at the bottom of the column should be close or similar to the boiling temperature of the solution in the pot, and it should reduce continuously in the column until it reaches the boiling point of the more volatile component at the top of the column. If the distillation flask is heated too quickly, the whole column will heat up almost distributively and eliminate the desired temperature gradient. The result will be little fractionation and separation of the components.
Answer:
0.79014 J
Explanation:
According to the first law of thermodynamics:-
Where,
U is the internal energy
q is the heat
w is the work done
From the question,
q = 0 J
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 3 - 1 L = 2 L
P = 400 Pa
The expression for the conversion of pressure in Pascal to pressure in atm is shown below:
P (Pa) = 
P (atm)
Given the value of pressure = 43,836 Pa
So,
400 Pa = 
atm
Pressure = 0.0039 atm
Also, 1 atmL = 101.3 J
So,
(work is done by the system)
So,
the nucleus represented by x is 56
Compound - made out of two or more types of elements chemically combined
Mixture - two or more substances in which the substances retain their identity
Element - simplest form of matter that is present by itself
