Integrated ConceptsA prankster applies 450 $\mathrm{V}$ to an 80.0$\mu \mathrm{F}$ capacitor and then tosses it to an unsuspecting victim. The victim's finger is burned by the discharge of the capacitor through 0.200 $\mathrm{g}$ of flesh. What is the temperature increase of the flesh? Is it reasonable to assume no phase change?

All right, so in this problem, we have a capacity. Oh, Ah. Who's the best is C E quo? Ah, 80 micro verities into the total. Ah, body across the capacity A C V equal for 50 volts. So if we connect this quest, that was the fingers and want to know that what happened? So basically, as we already know the sea and the V, we can find out to the total Energy authority in this capacity vehicle energies e equal off time. See, Time's be squid. Okay. And this gives you 8.1, Jules. So that means Ah, If this capacity is connected to the fingers, the fingers, then ah, the April 1 Joe's energy will be transferred to this. Ah, the finger. And we know that the total the effective mass of the finger is not effective. A mess on the finger right here is just the point, too. Went to Gram's. Yeah, So want to find other temperature increase of this flash? It's basically ah, the specific keys off the flesh is Ah ah, See quo 3.5 grams. Ah, sorry, Joe. Program times. Kelvin. Okay, so this is Ah, we can figure out the total energy. Ah, in the other expression so equal See time's m times that a t we received the specific heat of the fresh right here on AM ease The effective mess which is this 0.2 grams and the devotee is the temperature increase for this fresh. And, uh and these energy, which is April 1, does. And it will see that that that a t here equal 11.6 Celsius degrees. So that means even finger is connected to this. Ah, faster than the temperature will be increased by 11 points. 60 Celsius degrees. So this very high, it's enough to get the finger burnt, but ah, but it will not course the phase transition, okay?
