A substance can be sprayed onto crops to prevent frost from forming. If frost didn't form...
To help prevent frost damage, 4.80 kg of 0°C water is sprayed onto a fruit tree. (a) How much heat will be released by the water as it freezes? kcal (b) How much would the temperature of the 200 kg tree decrease if it lost this amount of heat, given its specific heat is 0.800 kcal/kg·°C, and no phase change occurs? °C
To help prevent frost damage, 3.20 kg of 0°C water is sprayed onto a fruit tree. (a) How much heat transfer in kcal occurs as the water freezes? (b)How much would the temperature of the 180 kg tree decrease in °C if this amount of heat transferred from the tree? Take the specific heat to be 3.35 kJ/kg · °C, and assume that no phase change occurs.
