Question

Given below are two statements.
Statement I: While baking in oven, a polished surface like shining tin or aluminum reflects the radiation heat, decreasing the amount of heat absorbed
Statement II: Cooking in oven takes place through steaming
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Hint:

To get a crispy, well-browned crust, use dark or matte bakeware because it absorbs more radiant heat.
Use shiny pans to prevent the bottom of delicate baked goods from burning.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Baking is a dry-heat cooking method that occurs in an enclosed chamber.
Heat is transferred to the food through a combination of radiation, convection, and conduction, and is influenced by the surface properties of the cookware.

Step 2: Detailed Explanation:
Let us evaluate both statements:
- Statement I: Polished surfaces reflect radiant heat.
This is correct. Shiny, polished metals like aluminum or tin have low thermal emissivity and high reflectivity.
When placed in an oven, they reflect a significant portion of the infrared radiation heat, which slows down heat absorption.
In contrast, dark, matte, or anodized pans absorb more radiant heat, leading to faster cooking and browning.
- Statement II: Cooking in an oven takes place through steaming.
This is incorrect.
Oven cooking (baking or roasting) is a dry-heat method that relies on the circulation of hot air (convection) and direct heat from the heating elements (radiation).
Steaming, on the other hand, is a moist-heat cooking method that uses the thermal energy of water vapor, typically performed in a closed steamer or pot rather than a standard baking oven.
Therefore, Statement I is true, and Statement II is false.

Step 3: Final Answer:
Statement I is correct because polished cookware reflects radiant heat, and Statement II is incorrect because baking is a dry-heat method, corresponding to Option (C).
