Final answer:
Ceramic is ideal for electric stove tops due to its insulating properties which provide a balance between effective heat transfer and surface safety, by maintaining lower conductivity than metals but higher than that of good insulators. the correct answer is c) Insulating properties.
Step-by-step explanation:
The ceramic used in flat surface electric stoves is an ideal choice for the stove top because it has insulating properties that are neither too high like good insulators nor too low like metals. The ceramic has a lower conductivity compared to metals, which means it doesn't transfer heat as efficiently, allowing the surface a few centimeters away from the heating element to remain cool enough to touch safely.
Meanwhile, it has higher conductivity than good insulators, ensuring that the heat from the element below can still pass through it to warm the pot above. Ceramics are similar to glass and brick in terms of thermal conductivity, which allows for a controlled heat transfer.
The properties of ceramics make them effective for balancing heat distribution and safety. Plus, their smooth surface makes them easy to clean, adding a practical aspect to their functionality.
This control of heat conduction makes ceramics suitable for use in kitchen appliances where heat transfer needs to be managed carefully, as indicated by cooking utilities typically made from good conductors while the handles are made from good insulators.
