Answer :
The specific heat of tin calculated from the given data is approximately 0.206 J/g°C.
To calculate the specific heat of tin, we can use the formula Q = mcΔT, where Q is the energy change, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
In this case, the energy change (Q) is given as 38.6 Joules, the mass (m) is 10.5 grams, and the temperature change (ΔT) is 39.4 °C - 21.0 °C = 18.4 °C.
Plugging these values into the formula, we get:
38.6 J = (10.5 g) * c * (18.4 °C)
To solve for c, we divide both sides of the equation by (10.5 g * 18.4 °C):
c = 38.6 J / (10.5 g * 18.4 °C)
Evaluating the expression, we find that the specific heat of tin calculated from the given data is approximately 0.206 J/g°C.
