பரப்புக் கவர்ச்சி (ADSORPTION) என்பது ஒரு புறப்பரப்புப் பண்பாகும். கரைசல்களின் புறப்பரப்பில் இப்பண்பு காணப்படுகிறது. ஒரு திரவம் அல்லது திண்மத்தின் பரப்பின் மீது ஒரு சேர்மத்தின் செறிவு அதிகரிப்பதே பரப்புக் கவர்ச்சி ஆகும். மேலும் இதனை அணுக்கள், அயனிகள், இரட்டை மூலக்கூறுகள் அல்லது வாயு மூலக்கூறுகள், திரவம், கரைந்த திண்மங்கள் ஆகியவை ஒரு பரப்பின் மீது ஒட்டிக் கொள்ளும் பண்பு என்றும் கூறலாம். இரண்டு நிலைமைகள் சந்திக்கும் எல்லையில் ஒரு சேர்மத்தின் செறிவு இரண்டு நிலைமைகளிலும் உள்ளதை விட அதிகமாக இருக்குமானால் அச்சேர்மம் பரப்பினால் கவரப்பட்டுள்ளது எனலாம். இப்பண்பையும் பரப்புக் கவர்ச்சி எனலாம். வாயுவையோ ஆவியையோ கரைசலிலுள்ள கரைபொருளையோ எடுத்துக் கொள்ளும் திண்மம் பரப்புக் கவரும் பொருள் (ADSORBENT) என்றும் திண்மத்தின் புறப்பரப்பில் படிந்துள்ள வாயு அல்லது கரைபொருள் பரப்புக் கவரப்பட்ட பொருள் (ADSORBATE) என்று அழைக்கப்படும். பரப்புக் கவர்ச்சி இரு வகைப் படும். அவை இயல்பு பரப்புக் கவர்ச்சி மற்றும் வேதிப் பரப்புக் கவர்ச்சி இயல்பு பரப்பு கவர்ச்சி என்பது பிணைப்பு அற்றது மற்றும் வலுவற்றது. வேதி பரப்புக் கவர்ச்சி என்பது பிணைப்புகொண்டது மற்றும் வலுவுடையது.Explanation:

The process of photosynthesis is commonly WRITTEN as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six CARBON dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.First, as seems obvious, chemical reactions are linked to change but not all change involves a chemical reaction. When liquid water boils or freezes it undergoes a change of state (a phase change), but the water molecules remain intact - they are still discrete water molecules, H2O.Paper makers must remove the lignin from the WOOD pulp. To accomplish this, ONE of the main chemical reactions USED in industry is the Kraft process, in which wood chips are combined with a mixture of sodium hydroxide and sodium sulfide in water at high temperature and pressure.When the bacterium Lactobacillus is added to milk, it breaks down the lactose present in the milk to lactic acid. This increases the acidity of milk and urges the casein to coagulate. Lactobacillus uses lactose to fulfill its energy requirements. Hence, this change is irreversible
