The answer should be C/Currents
I think its a hope that helped :)
IT IS NOT POSSIBLE to produce malleable cast iron in pieces having large cross sectional dimension. This is because, iron has a very rapid cooling rate and it will not be possible to achieve this rate at different cross sectional areas in a sheet of iron.
Answer:
The iodine might have got into the bag by the process of diffusion/osmosis.
<em>In the process of diffusion, particles move from an area of higher concentration to an area of lower concentration along a concentration gradient. </em>
As we know, the iodine solution in the large container had more particles of iodine whereas the baggie had none of the iodine solution. As a result, a concentration gradient developed due to which iodine solution moved into the baggie through the process of diffusion or osmosis.
