Atub containing 53 kg of water is placed in a farmer's canning cellar, initially at 10∘c. on a cold evening the cellar loses thermal energy through the walls at a rate of 1200 j/s. without the tub of water, the fruit would freeze in 4 h (the fruit freezes at −1∘c because the sugar in the fruit lowers the freezing temperature). part a by what time interval does the presence of the water delay the freezing of the fruit? the specific heat of water is c = 4180 j/kg⋅∘c.
