The rate of evaporation of a liquid increase on heating . Explain

Posted by Rupsa Mal 4 years, 7 months ago

CBSE > Class 09 > Science

1 answers

Sia ? 4 years, 7 months ago

Evaporation basically means the surface liquid gets enough kinetic energy to change into gaseous state. Definition: when the surface pressure of a liquid is equal to the vapour pressure of the atmosphere, it evaporates.
When we heat a liquid, we give it energy, n hence, the (kinetic) energy of the liquid increases, (so consequently the kinetic energy of the surface liquid also increases.

Savita Singh 4 years, 7 months ago

Prokaryotic Cells: In some organisms like bacteria, the nuclear material is not enclosed by nuclear membrane and membrane bound cell organelle are absent.Such nucleus is called nucleotid and such cells are known as prokaryotic cell. such cells have single chromosome. Eukaryotic Cells: Cells having well defined nucleus and having membrane bound cell organelle is termed as eukaryotic cell.Such cells have more than one chromosomes.

Particles of matter are continuously moving. They possess kinetic energy. Aa the temperature increases, particles move faster. The particles of aroma diffuse in the air and reach to us several meters away. But to get smell of cold food we need to go closer because the particles of aroma move slowly.
