Answer question 4 please. Make sure it’s correct and explain the steps please.
An alloy begins melting at a certain temperature called the liquidus and finally completes the transformation to the molten state at a higher temperature called the solidus. Question 25 options: True False
Q4. Answer FIVE of the following statements with True or False with explanation for each: 1. Water has higher critical values than that for helium molecules. 2. Liquefaction of gases is only occurred when we have low temperature and high pressure as external effects. 3. Amorphous solids characterized by lower water solubility than anhydrous crystalline solids. 4. Melting point for even number alkanes is more than that for odd number. 5. Mesophase is the same as the supercritical liquid. 6. The ternary systems can be represented by both planar and triangular diagrams.
Question 1: (answer must be handwritten) Indicate whether the following statement is true or false. Explain your answer (Maximum 3 lines). Air can always be regarded as a pure substance.
6. A block of iron initially at 800 °C is to be quenched in a water tank initially at 10 °C and 100 kPa (same as atmospheric pressure). If the iron block weighs 20 kg, what is the minimum amount of water required to avoid boiling. The water pressure is kept at 100 kPa ( same as atmospheric pressure).
i think question 1 and 8 us True. what do you think ?
STEP 2 Your first customer asked for an air piston-cylinder to use it in air compressors for generating high pressure. Your role in your company is to analyze, describe the operation of the system and their properties, explain and demonstrate the application of the first law of themodynamics to this system, as well as, illustrate the importance of expressions for work done in the system through the application of the first law. Describe the operation of the themodynamic system in Figure 1 and its properties, by constructing a P-V and T-V plots showing the process, the path, and the states then show the work under the curve on the P-V plot. STEP 3 Explain the application of the first law of thermodynamics to the system and explain the system parameters in terms of energy forms changes using the non-flow energy equation (NFEE) for the system and how they affect other parameters such as the final air temperature, by stating the appropriate assumptions and writing the general formula and…

Q1/ Draw a thermal equilibrium diagram for the binary alloy system (Si -Au), from the following data:- a- Si melts at 1414 °C, and Au melts at 1064 °C, and identify all phases are present in the diagram. b- Eutectic is formed at 360°C containing 20 Wt% Si -80 Wt% Au. c- Determine the amount of each phase for the alloy which consist 60 Wt% Si- 40wt % Au at 1200 °C and 800 °C ,then determine the amount of eutectic at 200 °C?
Q3/ Draw thermal equilibrium diagram for the binary alloy (Pb- Sn) from the following data :- Lead melting at 327 °C, Tin melting at 232 °C, and the eutectic mixture consists of (61.9 wt% Sn- 38.1% Pb) at 183 °C. The maximum solubility of Sn in Pb 19.5 wt% at 183 °C, but the maximum solubility of Pb in Sn 2.6 wt% at 183 °C, and the solubility limits to each other's decreasing to zero at room temperature.
