The temperature of water increases by 10 °C when it is heated during a thermodynamic process. What is the temperature increase in Kelvin (K)?

10 K

Explanation:

Given that

Temperature rise of water = 10°C

Lets take initial temperature =T₁

Final temperature = T₂

Rise in temperature = T₂ - T₁

T₂ - T₁ =  10°C

We know that conversion of temperature unit is given as

K= 273+ C

Initial temperature in kelvin =T₁ +273

Final temperature in kelvin =T₂ + 273

The increase in temperature =  (T₂ + 273 )-(T₁ +273 )  = T₂ - T₁

Therefore the increase in temperature in Kelvin will be 10 K.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask
