A Bunsen burner is a device used for heating in laboratories, with a vertical gas nozzle and adjustable air inlet for controlling the flame. A gas cooker hob is a kitchen appliance for cooking food, with multiple burners for heating pots and pans. The main difference is in their design and intended use, with the Bunsen burner being more specialized for scientific purposes.
It is so because the handle is of the metal and metal are good conductors of the heat. so to escape from the heat while catching the handle hard plastic is used.
Plastic pipes like PEX are commonly used for water supply lines in residential homes and are known for their durability and resistance to leaks. However, it is important to follow manufacturer guidelines for installation to minimize the risk of leaks. When it comes to using a plastic pipe with a finned radiator for heating, it is not recommended because plastic pipes may not withstand the high temperatures involved in a heating system. It is safer to use metal pipes specifically designed for heating applications.
The formula you are looking for is Amps = kW x 1000/1.73 x Volts x pf. The pf (power factor) of resistance heating will be 1. If the cooker was rated in kVA the same formula would be used minus the pf.

Plastic bowls should not be used to heat on a cooker because they can melt, release harmful chemicals, or start a fire. It is safer to use heat-resistant materials like glass or ceramic for heating on a cooker.

In a cooker. Unless you're using a 'halogen' cooker - the heating elements on the hob and within the oven and grill are simply large resistors, that heat up when power is applied.
A freestanding gas cooker, also known as a gas range or gas stove, can be used for quite a multitude of various things which can range from cooking food to heating a certain space.
A plastic welding machine is used on vehicles to heat up and mold plastics. Though there are many other machines that specialize in heating plastic as well.
The black plastic used in plastic handles are a thermosetting plastic, typically Bakelite. Many other types of plastic, called thermoplastics will wilt and deform on heating.
It can be used in several forms, directly and indirectly. For example, you can sit in the sunlight to get warm. We use it at home for cooking (with a solar cooker), and for heating water, which we use mainly for taking showers (with a solar water heating system).
It depends on what you are using the bowl for. Amend your question and then it can be answered in a more positive way
it is made out of thermoplastic
Three basic materials that can be used to build a solar cooker are cardboard, aluminum foil, and glass. Cardboard serves as the structural framework, while aluminum foil reflects sunlight to enhance heating. A sheet of glass can be used to create a greenhouse effect, trapping heat inside the cooker. Together, these materials can effectively harness solar energy for cooking.
Plastic is used in molding processes by heating it until it becomes soft and then shaping it into a specific form using a mold. Once the plastic cools and hardens, it retains the shape of the mold, allowing for the production of various plastic products.
