Is plastic a better insulator than metal?
No, it is not. Metals conduct heat much better than most plastics. However, if the metal is used as a reflector of radiated heat, it will insulate better than plastic would.
Why the plastic handle used in the pressure cooker doesn't melt?
there are two types of Plastics. the Thermoset and the Thermoplast. these Plastics all Melt, but @ different temperatures. the Thermoplast melts easily and can be recycled, while the thermoset has a property that makes it difficult to melt @ the temperature of the cooker that is being heated.this therefore explains why the Plastice does not melt because its thermoset Plastic and It has a higher temperature
What are three good insulators of heat?
Three good insulators of heat are, maybe plastic, wood and glass! That's all I can think of right now but plastic and wood are very good insulators (etc. used of saucepan handles)
What are the bad conductors of heat?
Any insulator - just think what kinds of material are used to protect people from heat: Oven gloves i.e. cotton Pan handles i.e. rubber and plastic Nuclear reactors are surrounded by 10m of water to insulate the thermal heat Asbestos used to be used for insulation The list is endless!
Which instrument is used to mearsure the heat?
which instruments used for the measurement of heat
Why are plastic bowls not used for heating on cooker?

Why are plastic bowl not used for heating on a cooker?

Which mirror is used in solar cooker?
a plane mirror is used in solar cookers so that the heat reflected by the mirror to the cooker should be same as the light(heat) given out by sun. hope dat helped
Why is the handle of the pressure cooker covered with thick plastic?
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.
What is the function of solar cooker?
The solar cooker has three major functions. The first function is concentrating the light from the sun into one small area. Reflective materials are used to do this, and the result is that the heat is more concentrated in the solar cooker. The second function is turning the sunlight into heat. This is accomplished by using a substance that can absorb the heat from the sun and store it for cooking purposes. The third function is trapping the heat created by the sunlight. Trapping the heat helps to cook food more evenly and means that the solar cooker can be used on both hot and cold days.
What Machine is used to heat plastic?
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.
Can Shake N Bake be used in a slow cooker?

Why don't you use plastic spoons for cooking?
Plastic spoons aren't used for cooking because the heat in the pan might melt them, introducing the plastic to the food, ruining it. It can be used for putting the food on a plate, or for scooping ingredients into a pan, however. Anything that doesn't involve direct heat should be fine.
Where is resistance used in everyday life?
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.
What material you can use for heat insulation in plastic injection mould?
Usually heat insulation plate is used
What is a solarcooker?
A solar cooker is a parabolic disk used in hot countries with a relective surface which reflects and focuses the light and heat from the Sun and enables it to be used to cook food.
What is the most important material in pressure cooker?
Stainless steel; because it is non-reactive, durable, and can be used on any and all heat sources.
