d)forma bem definida e volume variavel​

The final temperature will be 31.85 °C

Explanation:

Step 1: Data given

Mass of water = 100.0 grams

Temperature of water = 6.7 °C

Mass of the other sample water = 100.0 grams

Temperature = 57.0 °C

Step 2: Calculate the final temperature

Energy Lost by the hot water = Energy Gain by the cold water

mass of hot water*c*(Temp. of hot water-x) = mass of cold water*c*(x-Temp. of cold water)

Energy Lost by the hot water=Energy Gain by the cold water

mass of hot water*c*(Temp. of hot water-x)=mass of cold water*c*(x-Temp. of cold water)

100*c*(57-x)=100*c*(x-6.7)

100*(57-x)=100*(x-6.7)

5700 - 100x = 100x -670

6370 = 200x

x = 31.85

The final temperature will be 31.85 °C
