Question

Hi plz answer this fast and dont write anything else if u cant then leave it for others

Answer 1

Explanation:

i) 50 ℃ = 273 + 50 =323℃

iii) steam burns are more severe than boiling water, because the enthalpy of steam is more than enthalpy of boiling water.

ii) evaporation is the process which takes at liquid-gas interface

boiling is the process which takes place at solid-liquid interface

iv) increase in temperature increases the molecular diffusion rate, hence temperature is directly proportional to diffusion rate.

Answer 2

°Kelvin

°Celsius °Kelvin

50.17 =323.32

50.18= 323.33

50.19 =

323.34

50.20 =323.35

1=50 °Celsius =

323.15 °Kelvin

2=Evaporation is the process of conversion of a liquid into vapor at a temperature below its boiling point. Boiling is the process by which a liquid turns into a vapor when it is heated at its boiling point. It occurs only at a particular temperature - boiling point

3= Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat

4=Diffusion always increases with an increase in temperature. Diffusion is caused by the movement of atoms or molecules from an area of higher concentration to one of lower concentration. Since heat increases the motion, then diffusion happens faster.
