Give reason for the following observation:
The smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you can have to go close.
The rate of diffusion is very high in case of gases. The particle of hot sizzling food mixes with the particles of air and reaches us several meters away. In case of cold food the food particles do not mix with the particles of air easily. The temperature increases the rate of diffusion. Hence we have to go close to it get the smell.
Convert the following temperatures to Kelvin scale.
35°C
To change a temperature on the celsius scale to kelvin scale. Add 273 to given temperature.
35°C = 35 + 273 = 308K
