In regarding nucleate boiling ________
.
the temperature of the surface is
greater than the saturation temperature of the liquid
bubbles are created by expansion of
entrapped gas or vapour at small cavities in the surface
the temperature is greater than that
of film boiling
all options are correct
the temperature is greater than that
of film boiling
Nucleate boiling in a type of boiling that takes place when the surface temperature is hotter than the saturated fluid temperature by a certain amount but where the heat flux is below the critical heat flux. The graphs shown below,
Nucleate boiling occurs when the surface
temperature is higher than the saturation temperature
Hence, the correct option is (C).
