Abimetallic strip consists of two metals: a on top and b at bottom. at temperature 00c this bimetallic strip was rigidly attached to the vertical wall with one end, so strip is horizontal. we know that coefficient of thermal expansion of metal a is less than coefficient of thermal expansion of metal b. temperature starts to raise. what happens to the bimetallic strip?

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
