In lab you submerge 100 g of iron nails at 40 0C in 100 g of water at 20 0 C. Specific heat of iron is 0.12 cal/g∙0C. Equate the heat gained by water to the heat lost by nails and show that the final temperature of water becomes 22.1 0C.

Let T be the final temperature of water and nails (iron).

Given that the initial temperature of 100 g nails, .

Specific heat of the iron, .

So, the heat lost by nails

The initial temperature of 100 g water,

Specific heat of water,

So, the heat gained by water

As the exergy is conserved, so

the heat lost by the nails = the heat gained by the water

From equation (i) and (ii), we have

Hence, the final temperature of both, iron nails as well as water, become .

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
