An ideal diatomic gas at 80 k is slowly compressed adiabatically and reversibly to half its volume. The final temperature is 104.8k
<h3>Calculation of final temperature </h3>
The formula used for compression is:-
TV^(γ-1)=C
where;
T= temperature=80k
V=volume(given volume is half of its original volume i.e v/2)
γ=CP/CV= ( 7.R/2)/(5R/2)=7/5
C= constant
using the given values in the formula;
80 x V^[(7/5)-1]=T(final) (V/2)^[(7/5)-1]
80=T(final) x (V/V2)^(2/5)
80=T(final) x (1/2)^(2/5)
T(final)= 80 x (2)^2/5
T(final)= 80 x 1.31
final temperature =104.8k

Answer:
1 mole
Explanation:
A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Chemical energy to thermal
Corresponding in size or amount to something else.
Answer:
2.881x10^23 atoms
Explanation:
From the studies of Avogadro's hypothesis, we discovered that 1mole of any substance contains 6.02x10^23 atoms.
Therefore 1mole of Fe contains 6.02x10^23 atoms.
Molar Mass of Fe = 56g/mol
56g of Fe contains 6.02x10^23 atoms.
Therefore, 26.8g of Fe will contain = (26.8x6.02x10^23) / 56 = 2.881x10^23 atoms
