The specific heat of mercury is 0.138 J/g Celsius. If 452 g of mercury at 85.0 Celsius are placed in 145 g of water at 23.0 Celsius, what will be the final temperature for both the mercury and the water?

Thus the final temperature for both the mercury and the water is

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = heat absorbed or released

= mass of mercury= 452 g

= mass of water = 145 g

 = final temperature = ?

  = temperature of mercury =

= temperature of water =

  = specific heat of mercury  =

  = specific heat of water=

Now put all the given values in equation (1), we get

Thus the final temperature for both the mercury and the water is

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
