- 36. In a heat engine, what material can we "theoretically" use as the working substance? (a) Only an ideal gas (such as air), due to their thermodynamic properties. (b) We can use liquids but not solids, since liquids can conform to the shape of their containers (engine), but solids cannot. (c) Any material which expands upon heating can be used.10.-What is the heat of the isothermal process (from point B to point C)?27) Which of the following must be true for a thermodynamic process that starts and ends at the same state? A: The total heat and work for the cycle must both be zero B: The total work equals the heat C: The value of all state functions must be different at the beginning and the end of the process D: The change in internal energy over the whole cycle must equal 0 E: The temperature of the system will be constant throughout the process
- 53. What is the decrease in entropy of 25.0 g of water that condenses on a bathroom mirror at a temperature of 35.0° C, assuming no change in temperature and given the latent heat of vaporization to be 2450 kJ/kg?Thermodynamics Question! Please and thank you for all your help! Please make sure the answer is valid and in the correct units!(1) - When a system changes from an equilibrium state A to another equilibrium state B, choose the correct statement for each of the quantities (i – iii): (i) Heat; (ii) Entropy; (iii) Work done by the system. Statements: " (a) "It's a quantity that is determined uniquely for states A and B.' (b) "It's a quantity that is determined by the change between states A and B, and also by specifying how the system changed from A to B."
