Applying 1st law of thermodynamics:
Q = Delta U + WB
WB is the workdone by the system
<span>WB = 346 J </span>
As,
<span>Delta U = ( m ) ( CV ) ( T2 - T1 ) </span>
<span>CV = ( Delta U ) / ( m ) ( T2 - T1 )
</span>Putting the values in equation:
<span>CV = ( 8485 J ) / ( 80.0 g ) ( 225 C - 25 C ) </span>
<span>CV = 0.5303 J / g - C degree </span>
Now putting in original equation:
<span>Q = Delta U + WB </span>
<span>Q = ( 8485 ) + ( 346 ) = 8831 J
8831J is the specific heat of the gas</span>
Answer:
conclusion
Explanation:
it can't be a hypothesis since tests are carried out to verify so it is not a theory
an introduction to an experiment only gives the basis of what we are investigating therefore nothing has been proven and the question is still unanswered
Because C-12 is fixed value of any organisms but the value of C-14 is constantly decreasing by time thats why every organism have their specific ratio of C14/C12
