Which of the following is true?
In a kitchen, aluminium vessels are used because aluminium is a good conductor of heat.
The correct answer is option 4: "In a kitchen, aluminium vessels are used because aluminium is a good conductor of heat."
Let's analyze each option:
- Option 1: This statement is false. Insulators resist the flow of heat, while conductors allow heat to pass through easily. They have opposite properties regarding heat transfer.
- Option 2: This statement is false. Wood is an insulator; it resists the flow of heat. This is why wooden handles are often used on cooking utensils.
- Option 3: This statement is false. Plastic, like wood, is an insulator and a poor conductor of heat.
- Option 4: This statement is true. Aluminium is a good conductor of heat. This property makes it ideal for cookware because it allows for efficient and even heating of food. The heat is quickly transferred from the heat source (stovetop or oven) to the food, leading to faster cooking times.
Therefore, the use of aluminium vessels in kitchens directly relates to its excellent heat conductivity.
