How much heat is required to warm 223 g of ice from -45.3°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
Calculate q,w,delta U and Delta H for each segment and for the cycle in which the direction of each process is reversed. In the graph all it says is the P initial =16.6 bar and Vinitial=1.00L and P final=16.6 bar and V final =25L
Calculate the change in internal energy of the system and determine whether the process is endothermic or exothermic: a) a balloon is heated by adding 850J of heat. It expands,
