Question

convert 80° c into kelvin scale and also define sublimation and evaporation

Answer 1

To convert °C to K just add 273.
And to convert K to °C subtract 273.

So ,
Your answer is
80+273=353K



Evaporation is the Change of liquid state into gaseous state.
Ex:-Boiling water



And sublimation is the change of solid state into gaseous state without changing in liquid state.
Ex:-Napthelene ball.

Answer 2

k = C °+ 273
k = 80° + 273 = 353 Kelvin ...

Sublimation - Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase....

Evaporation - Evaporation is the type of vaporization which occurs on the surface of liquid as it changes into gaseous phase...
