If you were asked to convert 25 cg to the unit hg, which of the following would be the first fraction used in the conversion? on
e hg over ten squared g ten squared cg over one hg ten squared hg over one cg ten to the negative second power g over one cg
1 answer:
We are asked to convert 25 cg to units of hg.
1 cg = 1 centigram = 10⁻² g
1 hg = 1 hectogram = 10² g
The options given are:
a) 1 hg/ 10² g
b) 10² cg/ 1 hg
c) 10² hg/ 1 cg
d) 10⁻² g/ 1 cg
To convert 25 cg to 1 hg, we could convert the 25 cg to grams first, then grams to hg.
25 cg · 10⁻² g/ 1cg = 0.25 g
Here we have converted our number from cg to grams. We can use another conversion of grams to hg to complete the conversion.
0.25 g · 1 hg/ 10² g = 0.0025 hg
Therefore, the first conversion we used was d) 10⁻² g/ 1 cg.

Answer:
ΔE = q + w
here q = -136 kj
w = 146
so ΔE = -136 + 146 = 10 kj
thus internal energy of system increases by 10 kj...
I hope this helps! :) I don't know if it's the right one
