** worth 20 points + brainliest ** a pan containing 40 grams of water was allowed to cool from a temperature of 91.0 °c. if the amount of heat released is 1,300 joules, what is the approximate final temperature of the water? a. 74 °c b. 78 °c c. 81 °c d. 83 °c

Answer : The correct option is, (D)

Solution :

Formula used :

where,

Q = heat released = -1300 J

m = mass of water = 40 g

c = specific heat of water =      

= final temperature = ?

= initial temperature =

Now put all the given values in the above formula, we get the final temperature of water.

Therefore, the final temperature of the water is,

- decrease the number of plants and animals living in the water.
