A physical property is any property that is measurable whose value describes a state of a physical system.A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom.The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. A period is the name given to a horizontal row of the periodic table.a group is a column of elements in the periodic table of the chemical elements.
The answer for this question should be B) Cleavage or the second option.
Answer:What kind of milk? What are the variables on your project? (I'm assuming it's an experiment)
Explanation:
Both of them are a hope this helps
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,
