Okay, how much energy is required to convert 125 grams of ice at 0 celsius to the water at 37 celsius? so for this one we have to convert into two processes.
00:25
The first is actually the 0 celsius of the ice melted becomes 0 celsius.
00:36
Of the water.
00:38
This is the first step.
00:40
And then the zero celsius water increases temperature.
00:46
Right? it becomes 37 celsius of the water.
00:52
So for the first step, the q1 involved simply equals to the heat of the vaporization and heat of the fureen times the morse of the water.
01:09
So we can check online what is the heat of fureen of water, right? fulene heat of fueling of water is about 34, so 340 kilo kilo per more.
01:55
And times more of ice, it's mass over the more mass.
02:00
So it's 340 times 1 to 5 over 18...
