Answer :
Final answer:
To calculate the initial temperature of the iodine, use the equation q = mcΔT. Substitute the given values and solve for T. The initial temperature of the iodine is 28.54°C.
Explanation:
To calculate the initial temperature of the iodine, we can use the equation:
q = mcΔT
Where q is the heat added, m is the mass of the iodine, c is the specific heat capacity of iodine, and ΔT is the change in temperature. In this case, we are given q = 48.8J, m = 10.4g, and ΔT = 35.9°C - T, where T is the initial temperature. The specific heat capacity of iodine is 0.214J/g°C. Substituting these values into the equation:
48.8J = (10.4g)(0.214J/g°C)(35.9°C - T)
Simplifying the equation:
T = 28.54°C
Therefore, the initial temperature of the iodine is 28.54°C.
