(a)
Interpretation:
From the Pb-Sn alloy cooling curve, the pouring temperature needs to be determined.
Concept Introduction:
A cooling curve is a line graph representing the transition from a stage of matter, normally, the curve shows the graph in terms of a gas to a solid, or a liquid to a solid. Time is the independent variable on the x-axis and temperature is the dependent variable on the Y-axis In the cooling curve, the amount of energy needed to change the phase is called latent heat. Also, the "cooling rate" at any stage is the slope of the cooling curve.
(b)
Interpretation:
From the Pb-Sn alloy cooling curve, the superheat needs to be determined.
