A piston/cylinder setup contains 1 kg of air at 20°C with an initial volume of V1=0.1 m3, as shown in Fig. Q7. Initially, the piston rests on some stops, but it is possible for it to move within the cylinder without friction. To lift the piston and start such motion, an air pressure of 1400 kPa is required. Now, heat is transferred to the system so that the temperature of the air reaches to a final value of 300°C. Fig. Q7 A. Which statement is true?

As some of you know, I am an aficionado of Starbuck's Steamed Milk, Venti size. Steamed milk is made by passing superheated steam into a stainless steel container containing the milk. Assume that the stcam is at 25C,L-$40 calories/gram, and the specific heat of steam is 0.500 calories/gram/degree C. Also assume that the milk is at 5°C and that 750 ml of milk represent the Venti size. The stainless steel container can be considered to have a mass of 400. grams and a specific heal capacity of 0.600 Jgram/K. If the density of milk is its specific heat is 4.184 Vgram/K, how many grams of steam does it take to raise the milk's temperature to a comfortable 65 C? Thank you for your help!
