Answer:
X=600 degrees celsius
Explanation:
We can evaluate by using the equation ==> Q=m(c)(delta T)
-We know the mass is 0.3 g
-Q= 66,300 J
-C= 390 j/g 0C
-Therefore, we need to solve for delta T (which will be represented by x)
Q= mct
66,300 J= 0.3 g (390 J/g 0C) (t)
The unit of measurement (g-grams) can be crossed out on the left side of our expression.
66,300 J=0.3(390 J 0C) (t)
-If we convert into a proportional relationship:
66,300 J 117 J/0C x
------------ = -----------
117 J/0C 117 J/0C
-Joules on both sides can be crossed off
*117 J/0C came from the product in terms of 0.3(390 J 0C)
*If we find the quotient of 66,300 J and 117 J/0C, we get 566.6 repeating
-You may keep the answer as it is, although for simplicity reasons, we can round to the nearest hundred.
-Therefore, x=600.
-----Remember, x represented the delta t in our equation. (I made notice of that when evaluating).
Hope this helps! :)
