BPSC AEDO l प्रेशर कुकर में खाना क्यूं जल्दी पकता है l Chemistry l Rahul sir #bpsctre4 #bpsc #tre4

In this very important Chemistry + Everyday Science session, Rahul Sir explains the scientific reason behind why food cooks faster in a pressure cooker, including concepts of pressure, boiling point, steam, and heat transfer.
This topic is frequently asked in BPSC AEDO, BPSC TRE 4, BPSC Prelims, Bihar Teacher, SSC, BSSC, and other science-based competitive exams.

📚 What You Will Learn
🔸 1. Why Food Cooks Faster in a Pressure Cooker?

✔ Because pressure increases inside the cooker
✔ Increased pressure → increases boiling point of water
✔ Water boils above 100°C (up to 120°C or more)
✔ Higher temperature → food softens faster
✔ Steam trapped inside provides moist heat, which cooks food quickly

🔸 2. Key Scientific Principles
✔ 1. Pressure–Boiling Point Relation

– When pressure increases, boiling point increases
– Food cooks at higher temperature → faster cooking

✔ 2. Steam Cooking

– Steam has high latent heat
– Transfers heat more efficiently

✔ 3. Closed System

– No heat loss
– Retains moisture
– Uniform heating

🔸 3. Benefits of Pressure Cooking (Chemistry + GK)

✔ Saves time
✔ Saves fuel
✔ Retains nutrients
✔ Uniform cooking
✔ Best for pulses, rice, vegetables

🔸 4. Daily Life Examples

✔ Hill stations → food takes longer to cook
(Because pressure is low → boiling point low)
✔ Pressure cooker solves this by increasing pressure

❓ Most Expected MCQs (BPSC / AEDO / TRE / SSC)

✔ Food cooks faster in a cooker because?
✔ Boiling point increases due to?
✔ At high altitude, water boils at?
✔ Steam contains which type of heat?
✔ What happens to pressure inside the cooker?
✔ Latent heat of steam helps in?
