Answer: The final temperature of the coffee is 43.9°C
Explanation:
To calculate the final temperature, we use the equation:
[tex]q=mC(T_2-T_1)[/tex]
where,
q = heat released = [tex]1.0\times 10^3J=1000J[/tex]
m = mass of water = 10.0 grams
C = specific heat capacity of water = 4.184 J/g°C
[tex]T_2[/tex] = final temperature = ?
[tex]T_1[/tex] = initial temperature = 20°C
Putting values in above equation, we get:
[tex]1000J=10.0g\times 4.184J/g^oC\times (T_2-20)\\\\T_2=43.9^oC[/tex]
Hence, the final temperature of the coffee is 43.9°C
