To help prevent frost damage, 4.00 ${kg}$ of $0^{\circ}{C}$ water is sprayed onto a fruit tree.(a) How much heat transfer occurs as the water freezes?(b) How much would the temperature of the 200-kg tree decrease if this amount of heat transferred from the tree? Take the specific heat to be 3.35 kJ/kg?$^{\circ} \mathrm{C}$ , and assume that no phase change occurs.
$\Delta T=0.002^{\circ} \mathrm{C}$

okay with this problem. We are looking at four kilograms of zero degrees Celsius water and we want to know how much heat transfer is occurring as this water freezes after its spread onto a fruit tree. So information we have is a mass of four kilograms and want to know the heat of freezing. So that's Q equals. M. Uh mass times latent heat coefficient l of fusion, which for water, if you look this up is strange in 34 killer Jules per kilogram. So for part A, we just have to multiply these so Q equals or killed rooms times the engine's air. Before kill, a juror was procured, which is 1300 36 Killer Jules, what you got? Part B is asking how much heat? How much would the temperature of the tree decrease if this amount of heat is transferred from the tree? So they give us that the tree is 200 kilograms. We're looking for adult T. They also give us a specific heat of 3.35 cure Jules per kilogram degree Celsius. And in this case, we want to use this heat equation. Master of specific heat times Delta t Rearrange it for Delta T. Since that's what the equation asks for on the heat, we just arguing used the heat from part, eh, That's 1336 killer Jules desired by 200 kilograms for the tree. Times 3.35 Killer Jules, the Kilogram Degree Associates units here. Cancel. We're just left with degree Celsius, and I get that This is about two degrees Celsius.
