Considering the three classes of response of materials to
changes in temperature, explain why it is a sudden change rather
than an accelerating or gradual change that is important for the
operation of a repeatable thermal cutout switch.
Explain the physicochemical changes that occur in soil due to
sodicity and how that leads to soil degradation.
(Note: You can use clear diagrams, chemical formulae and
relevant chemical equations)
How
and when does sex differentiation occur prenatally? What changes
can occur inutero that could lead a child to experience gender
dysphoria and/or gender non-conforming behavior? Do you agree with
the biological perspective of gender development/sexual
orientation?
As speed increases in an engine with throttle body fuel
injection, does the temperature of the air-fuel mixture at the
intake manifold exit increase or decrease? Explain what parameters
affect your answer.
Explain why does the peak emission wavelength of LEDs increase
(red shift) with temperature? Why does the peak emission intensity
decrease with temperature? Use sketches and curves for the
answer.
