A 0.011 kg cube of ice at 0.0 degree C is added to 0.450 kg of soup at 80.0 degree C Assuming that the soup has the same specific heat capacity as water, find the final temperature of the soup after the ice has melted. (Hint: That is a temperature change after the ice melts.) ​

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
