Question

A 1.00 kg piece of aluminum (Cp = 24.4 J/K*mol) at 500 oC is put into contact with 1.00 kg piece of copper (Cp = 24.4 J/K*mol) at 10 oC. Assuming no heat is lost to the surroundings, what is the final temperature of the system?

Answer 1

Answer:The molar heat capacity of solid aluminium is 24.4 J K-1 mol-1 at 25°C. Calculate the change in internal energy when 1.00 mol of solid aluminium is heated from a temperature of 20°C to 30°C.

a) The constant pressure molar heat capacity of methane (CH4) is 35.31 J K-1 mol-1 at temperatures close to 298 K. Calculate the enthalpy change when 2.00 mol of methane is heated from a temperature of 278 K to 318 K.
