Calculate the amount of heat water absorbs from a piece of hot metal using the following data: 75.0 g of cold water is placed in

a calorimeter. The initial temperature of the water is 21.2 oC. To the calorimeter a 29.458 g piece of metal at 98.9 oC is added. The final temperature of the contents of the calorimeter is measured to be 29.5 oC. (HINT: the specific heat of water is 4.184 LaTeX: \frac{J}{g\cdot K}

Answer:

Amount of heat absorbed by water is 2604.54 J.

Explanation:

Amount of heat absorbed by water = m_{water}\times C_{water}\times \Delta T_{water}

where m represents mass, C represents specific heat and \Delta T represents change in temperature.

Here m_{water}=75.0 g , C_{water}=4.184J/(g.^{0}\textrm{C}) and \Delta T = (final temperature - initial temperature) = (29.5-21.2) ^{0}\textrm{C} = 8.3 ^{0}\textrm{C}

So, amount of heat heat absorbed by water

     = (75.0g)\times (4.184\frac{J}{g.^{0}\textrm{C}})\times (8.3^{0}\textrm{C})

     = 2604.54 J

Reasons why water is a good cooling agent in machines​
Fiesta28 [93]

Answer:

one reason is, Water is a very good liquid for cooling things down, for one thing there is plenty of it and it has also got a high specific heat capacity. This means that it can absorb a large amount of heat energy without getting too hot.


will not heat up or cool down very fast

Water has a high value of latent heat of vapourization so it has cooling properties.
hope this helps you. :)
