An insulated system takes in 34.0 kcal of heat and has 2200 J of work done on it. Calculate the change in its internal energy.
Potassium nitrate has a lattice energy of -163.8 kcal/mol and a heat of hydration of -155.5 kcal/mol. You may want to reference (pages 551 - 555) section 12.3 while completing this problem. How much potassium nitrate has to dissolve in water to absorb 109 kJ of heat? Express your answer using two significant figures.
400 J of heat is added to a system. If the change in internal energy of the system was 850 J, how much work was done on by the system? the inside a container absorbs 250 J of hea while 125 J of work is done on it and then does 70 J of its own work, by how much does the internal energy of the gas increase? 7.500 joules of heat is added to a system while it also...
