the mass of the shells will remain the same because you can not change mass even if you were to leave this planet and go to the moon your weight would change but your mass remains the same
Q=mc(change in temp)
Q is amount of heat, m is mass, c is specific heat
Water:
Q= (50.0g)(4.18 J/g°C)(63°C)
Q= 13167J
Aluminum:
Q= (200.0g)(0.900 J/g°C)(63°C)
Q= 11340J
Water requires more heat
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,

B.Bones
They’re usually formed in the bone marrow
The atomic number tells you the number of electrons. That means there are 18 electrons in an argon atom.
