Who will cook vegetables faster and Y?
What is the reason for delay in cooking by Rohan?
What values is shown by Soman ?

Answer 1

a)The vegetable in pressure cooker cooks faster .i.e, by Soman.
He cooks faster because Pressure-cooking is a cooking method that uses steam sealed in a pressure cooker, which is a special airtight cooking pot. Pressure cooker traps the vapour that rises from the liquid. This in turn raises the pressure inside the pressure cooker along with the maximum temperature that the liquid can reach. The increased temperature and pressure significantly speed up the cooking process. The pressure infuses the hot steam into the food.

b) No such a speed up process occurs in normal boiling. So, Rohan used a open pan to cook vegetables which involve a boiling process. That's why there is a delay in cooking by Rohan.

c) Soman used a pressure cooker to cook his food. He shows the following values :
Time management : as he saves time by cooking food in pressure cooker and cook food in less time.
