The heat required to melt 185 g of ice at 0 C is given by :
QICE = ( mICE ) ( hsfICE ) = ( 185 g ) ( 333.7 J / g ) = 61734.5 J
QW = - QICE = ( mW ) (CshW ) ( - 1.0 C deg )
mW = ( - 61734.5 J ) / ( 4.184 J / g - C deg ) ( - 1.0 C deg )
mW = 14,750 g = 14.75 kg of water <-----
where
mICE is mass of ice
hsfICE is (specific) enthalpy of solid fusion, i.e. enthalpy per unit mass
Cshw is the "heat capacity" of water,
mW is mass of water
NOTE: the literature value for water at °C is actually 4.1858 J/g/°C, so the actual answer should be closer to 14.7485 (not exactly though since the temperature change would be from 15 °C to 14 °C so you would need the heat capacity as a function of temperature over that range, not just the isothermal value at 15 °C). Within the justifiable precision, it still rounds to 14.75 kg, just like the answer above so the error is negligible.

What is the process of water releasing heat called?
Evaporation. A body of water is cooled as a portion of it is converted to vapor by evaporation.
After heat is absorbed into a condenser medium in a water cooled condenser the heat can be deposited in one of two places what are they?
There is only one condenser. That would be an air condenser.
What will happen if hot water is cooled?
well whoever asked this is an idiot. obviously it's gonna get cool. wow. the heat from the hot water will be lost to its surrounding.
Why is it necessary to enclose the nuclear reactor at low pressure?
There is some sort of confusion here. There are two types of water moderated/cooled reactors: boiling water and pressurized water.The boiling water reactor is at normal atmospheric pressure and the water in the reactor boils, producing steam directly.The pressurized water reactor is at elevated pressure to prevent the water from boiling. A heat exchanger/steam generator is used to produce steam indirectly.Other types of reactor (e.g. liquid metal, gas cooled, organic, aqueous homogeneous) also do not operate at pressures below atmospheric.
Why heat must be lost before water turns to ice?
it has to be cooled because ice is cold not warm. it is impossible to make a warm ice cube
What two places heat can be deposited in in a water-cooled condenser?
what two places heat be deposited in a water cooled condenser
What type of heat pump coils are used outdoors?
Air cooled, water cooled and ground cooled
Does heat move in or out of water cooled below 0 degrees?
Out
Why and how does the water inside the chilled water pipes got cooled?
The heat gets removed from the H2O

How your body cooled when you perspire?
Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.
Fifty grams of water cooled from 50 degrees to 10 degrees if the specific heat of wayer is 4.2 hoe much was released?
If fifty grams of water cooled from 50 degrees to 10 degrees, and the specific heat of water is 4.2, 135 kJ of heat was released.
Why is the water used in the experimental procedures for the heat capacity of metals initially cooled several degrees below room temperature?
why is the water used in the exprimental procedures for heat capacity of metals initially cooled several dgrees below room temperature
Why will a cooled watermelon stay cooler on a hot day than other things of lower water content that have been cooled?
The water present in the watermelon will give the fruit moisture and will not allow the heat to react with it.
Does an under water volcano heat up the water?
if you are right above it properly yes but if you at the surface of the water it would have cooled down by the time it gets to you
Does the volume get larger when a solid is cooled?
no it expands with heat, it shrinks when cooled
What is a necessity in the process of Evaporationother than water itself?
Heat is necessary to evaporate water.
