Here in this problem we have temperature ts is equal to 85 degree centigrade, so changing it into kelvin.
00:09
So 85 plus 273 is equal to 358, 358 kelvin.
00:16
Also, temperature of water, tw is equal to 14 degree centigrade.
00:21
So changing it into kelvin, 287 kelvin.
00:25
And the temperature of silver, tf is equal to 25 degrees.
00:30
Centigrade is equal to 298 kelvin.
00:34
Now solving part a.
00:37
So for part a i will use the formula.
00:40
Number of plates is equal to mw into cw multiplication tf minus tw by ms -cs multiplication t -s minus t -f minus t -f.
01:05
So just putting the value here.
01:08
So i can write the expression as 0 .22kg, multiplication 4186, multiplication 298 kelvin, minus 287 kelvin, by 1 into 10 to the power minus 3 kg, multiplication 234, multiplication 358, minus 298 kelvin...
