What chemical can you use to melt lead?
Lead (or anything else) is melted by heat. There are various chemicals that can be used to produce heat. For example, a propane torch can melt lead.
The heat of fusion of lead is?
4.77
Is lead a better conductor of heat than glass?
Yes, lead is a metallic solid, and therefore facilitates the transfer of heat (energy) better than other solids.
How do you separate pure lead nitrate from lead oxide?
If you could get a high enough temp. you could heat it in a retort of some kind and collect the oxygen given off and lead would be left. The old school way was to heat the lead oxide on a block of carbon using a bunsen and blow pipe to provide extra oxygen for a hotter flame. The extra heat caused the oxygen from the lead oxide to combine with the carbon to form carbon dioxide and lead was left on the carbon block.
What is the observation when you heat lead nitrate crystals?
A thermally decomposition of the nitrate; the final products are lead oxide and nitrogen dioxide.
What color get the hottest from absorbing heat?
black as it is an excellent absorber of heat. that's why you feel very hot when you wear black coloured clothes. so many times we prefer to wear white clothes as white is an excellent reflector.
What is a reflector of heat?
For example aluminium.
Is gold the best reflector of heat?
yeah
What is good reflector of heat and light?
A mirror.
Is a good emitter of heat also a good reflector of heat?
Yes..
Why are oil tankers painted silver?
good reflector of heat
Why is a poor reflector of heat also a good absorber?
Common sense. Is something is reflected, it cannot be absorbed, and vice versa. If something is a good absorber of heat, it tries to "hold onto" as much heat as possible; if something is a poor reflector of heat, it is bad at minimizing heat absorption.
What traps heat in the solar cooker?
Usually mirrors or a large reflector traps the sun's heat and focuses it on the food.
How does dark colour absorb more heat than white?
White is a good reflector of heat therefore it will absorb less heat than a dark surface.
Why is there a shiny surface at the back of the radiator?
The shiny surface is a reflector, to reflect the heat outwards towards you.
What is the difference between a good radiator of heat and a good reflector of heat?
heat absober absorbs heat & refelector reflect it
What is fireplace reflector?
a vertical metal sheet that goes behind the fire to reflect heat back into the room.
