🤓 Based on our data, we think this question is relevant for Professor Salsbery's class at WWU.
A 31.5 g wafer of pure gold initially at 69.7 oC is submerged into 63.6 g of water at 27.2 oC in an insulated container.
What is the final temperature of both substances at thermal equilibrium?
In this problem, we’re being asked to determine the final temperature of both the substances at thermal equilibrium.
Recall that heat can be calculated using the following equation:
q = heat, J
• +q → absorbs heat
• –q → loses heat
m = mass (g)
c = specific heat capacity = J/(g·°C)
ΔT = Tf – Ti = (°C)
Recall that heat always travel from high-temperature object to lower-temperature object.
Based on the given system:
