q = mass H2O x heat fusion
You know mass H2O in grams, look up the heat fusion in J/g and solve for q in joules. The problem actually is not complete because it doesn't tell you the temperature of the water being sprayed. I think it assumes you will assume the temperature of the water when it hits the orange will be zero C (either that or that the water is cooled by the "frosty air" to zero and then freezes).
Water is sprayed on oranges during a frosty night. If an average of 11.8 g of water freezes on each orange how much heat is released.
Can you please help me set this problem up. I don know what formula to use?
thank you
