Question

A solar cooker and a pressure cooker both are used to cook food. Treating them as
thermodynamic systems, discuss the similarities and differences between them.​

Answer 1

Answer:

Solar cooker:

⋅ The Solar cooker was invented by Horace Benedict de Saussure in 1767.

⋅ The Solar cooker is a device used to cook food by using no fuel, instead of sunlight.

⋅ Solar cookers use a parabolic reflector to collect the rays of the sun and focus them on the cooker to heat it and cook the food in the cooker.

⋅ Today the solar cookers are a little bit expensive than pressure cookers.

⋅ Big solar cookers can be used to make food for people on a larger scale.

Pressure Cooker-

⋅ The Pressure cooker was invented by Denis Papin.

⋅ Pressure cookers are the most common cookers used in our houses and can be found in every house.

⋅ Pressure cookers require water to convert it into steam for raising the internal temperature and pressure that permits quick cooking.

⋅ Pressure cookers are cheaper than solar cookers.

⋅ Pressure cookers require fuel for heating the liquid inside them
