Answer:
ANSWER
(a) Triple-point has a unique temperature; fusion point and boiling point temperatures depend on pressure.
(b) The other fixed point is the absolute zero itself.
(c) Triple-point is 0.01

C.
(d) T=273.15×9/5=491.69
The temperature and pressure at which a substance can exist in equilibrium in the liquid, solid, and gaseous states.It is unique and constant. The problem with Celsius scale is that boiling and melting point change with atmospheric pressure at that place.
