Apan containing 30 grams of water was allowed to cool from a temperature of 90.0 °c. if the amount of heat released is 1,500 joules, what is the approximate final temperature of the water? 76 °c 78 °c 81 °c 82 °c

Option B, 78.05 °C is the approximate final temperature of the water

Explanation:

Heat released

Where "m" stands for mass of any substance

"c " stands for specific heat of water  is equal to 4.186 joule/gram °C

stands for final temperature

stands for initial temperature

Substituting the available values in above equation, we get -

78.05 °C is the approximate final temperature of the water

Thus, option B is correct.
