Answer:
25,190
Step-by-step explanation:
To find the heat transferred, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat (J/g·K)
-----> ΔT = change in temperature (K)
Since the specific heat has been given in terms of Kelvin (K), you technically need to convert the temperatures from Celsius to Kelvin (although your ΔT will still be the same). After doing so, you can plug the given values into the equation and solve.
73.9 °C + 273.15 = 347.05 K
17.4 °C + 273.15 = 290.55 K
Q = ? J c = 0.9025 J/g·K
m = 494 g ΔT = 347.05 K - 290.55 K = 56.5 K
Q = mcΔT
Q = (494 g)(0.9025 J/g·K)(56.5 K)
Q = 25,189.6775
Q = 25,190 J
