Answer:
1683.6J
Explanation:
Given:
n= no. Of mol= 2.70 mol
T= Temperature= 30.0 K
Q= n Cv × ∆T .........eqn(1)
Where CV= molar heat capacity=5/2R for diatomic particle ,such as H2
CV= molar heat capacity=3/2R for diatomic, such as H
R= gas constant= 8.314 J/mol.K
Q= heat energy
For a diatomic molecules
Q= n Cv × T
But
Cv= molar heat capacity=5/2R = 5/2(8.314)=20.785
CV= 20.785
. ∆T= Temperature= 30.0 K
Then substitute the values into the eqn(1)
Q= 2.70 × 5/2(8.314) × 30
Q= 2.70 × 20.785 × 30
=1683.6J
When there is a transfer of heat a wind usually blows from where the heat is transferred from
Answer:
The coefficient of thermal expansion α is
The coefficient of compressibility
Now considering 
From equation (1) we have that
From ideal equation
So
=> 
=> 
Explanation:
From the question we are told that
The coefficient of thermal expansion is 
The coefficient of compressibility is 
Generally the ideal gas is mathematically represented as
=> 
differentiating both side with respect to T at constant P
substituting the equation above into 
Recall from ideal gas equation 
So
Now differentiate equation (1) above with respect to P at constant T
substituting the above equation into equation of 
Recall from ideal gas equation that
So
Now considering
From equation (1) we have that
From ideal equation
So
=>
=>
Experimental errors can be of two kinds: human error and analytical error. Analytical error can be corrected easily. You just have to use instruments that are of high precision. For example, instead of using the platform balance, use the analytical balance which displays 4 decimal places to be highly accurate. For the human error, this is subjective. The only way to correct human error is to be more meticulous on your data measurements.
Answer:
Some of the orbits are nearly circular, while the moons farthest from Jupiter have more irregular orbits. The outer moon's orbit in the opposite direction in which Jupiter spins, which is unusual and indicates the moons were asteroids that were sucked into Jupiter's orbit after the initial system was formed.
