(a) A person drinks four glasses of cold water (3.0 $^{\circ}$ C) every day. The volume of each glass is $2.5 \times 10^{2} \mathrm{mL} .$ How much heat (in kJ) does the body have to supply to raise the temperature of the water to $37^{\circ} \mathrm{C},$ the body temperature? (b) How much heat would your body lose if you were to ingest $8.0 \times$ $10^{2} \mathrm{g}$ of snow at $0^{\circ} \mathrm{C}$ to quench thirst? (The amount of heat necessary to melt snow is $6.01 \mathrm{kJ} / \mathrm{mol} .)$

Careful The solution. Uh, this is the box. And here they put a ice cube and this is ah, beverage at 80 degree Celsius. Now from here now, as soon in the other fear as you can see, the beverage and I system is isolated to not hot transfer by heat. So the surroundings here, these are isolated to know to transfer heat to the surrounding No, for her food. Here we have 2 to 6.7 and 6 g now heat lost by Beveridge Equal toe heat gained by the eyes by the melting at 0.1 degree sensors. That is triple point off eyes here for decoration. MBI CPI even minus three to equal to AM ice Delta. Edge is he goes to energy balance. No. By putting the value and simplifying this equation we get and ice wish, Toby milk is equal to 0.3819 kg. Here, most of the ice Toby meld in order to bring the Berries 38.19 g from 18 degree toe, four degree health. This is answer. Thank you. Yeah,

Here we are taking a look at a sublimation process where E. Of sublimation people to E. Of mounting at E Ev vaporization. The energies Where we can determine the mass of four ice cubes which is equal to four. Multiplied by 60.1 g. The mass of an ice cube we have to 40.4 g. Where the energy of melting Is equal to the mass of the four ice cubes. to 40.4 g. multiplied by 333 jewels per graham. We got 8005 3.2 jewels. Yeah. Next we can look at the energy of vaporization. He faith pres ation. That's equal to the mass of the ice cubes to 40.4 g. multiplied by 2260 jewels program Which is equal to 54,330 for Jules. So the energy of sublimation is these two values added together. Mhm. What we get is 6.23 times 10 to the five jewels

So we know that the energy of sublimation is equal to the energy of the mounting and the energy of vaporization. And so the energy of mounting is equal to the massive four ice cubes, Multiplied by 333 jewels per gram Is equal to 8005 3.2 jewels. The energy of vaporization is, he. Put the maps for ice cubes multiplied by 2260 jewels, divided by one grand. We got 543304 jewels, and so we had these two bodies together here for the energy of sublimation, Which is equal to 6.23 times 10 to the five jewels.

Now we goto 80 81. I did want Now we apply the formula Update of fusion. Okay, so I do What? Okay. Can I have it? Or fusions? We had killed equal the outer edge Fusion. I am right. So now want to find the edge of fusion? We had this. There was extra fusion. He could kill over him and kill. We have already harmony this ICO seven 39 kg calories and the mosque equal 92 from Popeye's. Okay. Mhm. Okay, You know what? This one, we can convert this toe bigger with unity calories over Graham. So we had to complete the toe calories. Okay. Mhm. Mhm. And then when we couple like this, we will have this week. Oh, 80 calories. But I did calories on Lee once it fit. But you got right here to sit fit, so he had a gender it into exponential notation. Just you realize this You got a specific line 92. Okay, so you have no notice when you do the problem?
