Answer:
24.53 °C
Step-by-step explanation:
To find the final temperature, you need to use the following equation:
Q = mc(T₂ - T₁)
In this equation,
-----> Q = heat (J)
-----> m = mass (g)
-----> c = specific heat (J/g°C)
-----> T₂ = final temperature (°C)
-----> T₁ = initial temperature (°C)
Using the given values, you can rearrange the equation and simplify to find "T₂".
Q = 950.0 J T₂ = ? °C
m = 680.1 g T₁ = 24.20 °C
c = 4.184 J/g°C
Q = mc(T₂ - T₁) <----- Given equation
950.0 J = (680.1 g)(4.184 J/g°C)(T₂ - 24.20°C) <----- Insert values
950.0 J = 2845(T₂ - 24.20°C) <----- Multiply 680.1 and 4.184
0.3339 = T₂ - 24.20°C <----- Divide 950.0 by 2845
24.53 = T₂ <----- Add 24.20 to both sides
