RELATION BETWEEN PRESSURE AND BOILING POINT

THIS PRESENTATION IS ABOUT THE RELATION BETWEEN PRESSURE AND BOILING POINT.THE RELATION IS EXPLAINED IN SIMPLE UNDERSTANDABLE WORDS.

1. RELATION BETWEEN PRESSURE AND BOILING POINT BY: JOHNS JOSEPH

2. WHAT IS THE BOILING POINT OF WATER ?

3. WE ALL HAVE A COMMON ANSWER

4. BUT IT IS 100 DEGREES CELSIUS AT 1 ATMOSPHERE PRESSURE

5. AS THE PRESSURE CHANGES THE BOILING POINT WILL ALSO CHANGE

6. WATER BOILS AT 76 O C ON MT. EVEREST AT 0.333 ATMOSPHERE PRESSURE

7. AS THE PRESSURE DECREASES THE BOILING POINT WILL ALSO DECRESASES

8. FOR PROPER COOKING PROPER TEMPERATURE IS REQUIRED

9. THE PRESSURE COOKER WAS INVENTED BECOUSE OF THIS REASON

10. PRESSURE COOKER WORKS BY KEEPING THE VOLUME CONSTANT AND INCREASING THE PRESSURE AS THE  PRESSURE  RISES, THE TEMPERATURE OF THE WATER AND STEAM INSIDE THE   PRESSURE COOKER ALSO RISES ABOVE THE NORMAL 100ºC (212ºF) BOILING POINT TEMPERATURE.  HIGHER THE  PRESSURE , THE SHORTER THE  COOKING  TIME.
