Why do irons have plastic handles?
(a) Curling irons and clothes irons have plastic handles because plastic isnot a good conductor I heat. ... This will ensure an even temperature across the bottom of the p1ulting in a uniform transfer of heat into the food.
Why are the handles of electrical appliances made of plastic?
Handles of electric appliances are made up of plastic as electricity passes /conducts through metal while it does not conducts through plastic as it is an insulator. Hence, handles of electric appliances are made up of plastic.
Which handle is not suitable for electric iron?
Answer: Electric irons are made of iron, and since iron is a good conductor of electricity, if you touch it with your bare hands you would get shocked. Plastic doesn't conduct electricity and is one of the best insulators, so it would be safe to use plastic handles while ironing.
Why is bakelite used in making handles of electrical iron?
we use bakelite or plastic as handles of electrical iron because PLASTICS and BAKELITE (also a form of plastics thermosetting plastics) because they are poor conductor of electricity and heat..
Do curling irons have chemical energy?
Electrical energy is transformed to heat energy when the curling iron stays on. Heat energy is transferred to the hair that is being curled. Light energy from the sun is transformed to chemical energy as the plants grow.
Why is heat radiation vastly different from conduction and convection?
Conduction usually occurs in solids, through molecular collision. Convection occurs in fluids by mass motion of molecules in the same direction. In contrast, Radiation takes place through the vacuum of space and does not heat up the intervening medium. ... The speed of conduction and convection is slower than radiation.
Which material is used in electric iron?
Nichrome is used as a heating element in an electric iron. It is an 80 per cent nickel and 20 per cent chromium alloy with nickel and chromium.
What is the strategy used in electric irons to control the heating?
The thermostat in iron generally uses a bimetallic strip. ... In this way, a bimetallic band functions as a kind of bridge to connect or switch off the circuit to regulate the heating. This cyclical switching on and off of the iron is repeated until you switch off the power supply from the main power source.
Who invented electric iron?
The invention of the electric iron coincided with the widespread electrification of American homes in the 1880s. In 1882, Henry W. Seeley of New York City received a patent for the electric flatiron. His model had built-in coils and was heated on a rack.
What is the difference between bakelite and plastic?
Bakelite is the first synthetic plastic and is known as a “material of thousand uses” due to its versatile applications. ... The key difference between Bakelite and plastic is, Bakelite is the first synthetically produced thermosetting plastic with heat resistant and non-conductivity of electricity.
Why was Bakelite discontinued?
Bakelite applications in conservation were discontinued in the 1940s because of certain disadvantages that soon became apparent. The lack of records and relevant information precludes any assumption on the extent of its use and in which institutions.
What is the difference between bakelite and melamine?
Bakelite is a thermosetting plastic and it is not easily molded again while Melamine is a thermoplastic and can be reshaped or molded again. Bakelite is a synthetic (man-made) material while Melamine is an organic or natural material.
Why is plastic used in the making of electric equipment such as switches and hair dryer?
Plastics are especially suited for material such as hairdryers, electric razor and food mixers as they protect the consumer from the risk of getting electric shock. ... To further protect consumers, plastics can be made fire resistant through the use of special flame retardant additives. Thus, the correct option is C.
What would happen if I left my curling iron on?
If it happens only once in a while, the curling iron should not be damaged. However, if you leave it on frequently, you'll risk shortening the life of the iron. As a safety measure, and to prevent any possibility of fire hazard, unplug your curling iron after using it.
Can curling irons start fires?
According to the U.S. Consumer Protection Safety Commission, 700 fires in 1998 were caused by Curling Irons and Hair Dryers. Curling irons are often the last item to be used before leaving a home. The maximum temperature of most curling irons is between 300° F and 450° F.
Do curling irons turn off by themselves?
Yes, the curling iron turns off automatically if left unattended.
