Before the advent of electricity, chemists used various methods to heat substances, including open flames from gas burners or alcohol lamps. They also employed coal or wood fires, as well as hot plates heated by these traditional fuels. Additionally, other techniques like sand baths or water baths were used to provide more controlled heating. These methods allowed for the gradual and even heating of materials in laboratory settings.
What else can I help you with?
Is the substance that readily conducts electricity and heat?
Yes, metals are substances that readily conduct electricity and heat due to their free electrons that allow for the flow of electricity and energy. Other examples of materials that conduct electricity and heat well include graphite and some types of ceramics.
What is the cunductor of heat and electricity of iron?
what is the conductor of heat and electricity of iron
Is conductors of heat and conductors of electricity the same thing?
Sometimes. Metals will conduct both heat and electricity. Glass will conduct heat but not electricity.
What substances is a bad conductor of electricity but a good conductor of heat?
Thank you but is there any other substances that can fit this criteria, particularly any metals. I need to be able to use this substance in extension cords so the substance needs to be inexpensive and common.
Is radon a good conductor of electricity and heat?
Refer to the periodic table of elements and check if radon is a metal or not. If it is a metal then it will be good conductor of heat and electricity. If it is a gas it will not be good conductor of heat and electricity
What are goods and bads?
Substances that don't have the capacity to carry heat are called bad conductors of heat (or insulators ). Substances that have the capacity to carry heat are called good conductors of heat. As for electricity, it is very, much the same.
What was coal used for before electricity?
Before electricity, Coal was used for heat. Coal heat was used to create steam for steam engines on railroads and ships in transportation.
Is the substance that readily conducts electricity and heat?
Yes, metals are substances that readily conduct electricity and heat due to their free electrons that allow for the flow of electricity and energy. Other examples of materials that conduct electricity and heat well include graphite and some types of ceramics.
How did you heat your homes before electricity?
Before electricity, people heated their homes using fireplaces, wood-burning stoves, coal stoves, and oil lamps. These sources of heat provided warmth and light for cooking and heating water.
Substance which conduct electricity but not heat?
Graphite is an example of a substance that can conduct electricity but is a poor conductor of heat. This is because of its unique structure, where it has delocalized electrons that can move freely to conduct electricity, but the heat energy is not easily transferred through the material due to weak intermolecular forces.
What has to happen to nuclear before it cam be used to generate electricity?
The nuclear reaction produces heat The heat is used to make steam The steam makes the turbines spin The turbines make electricity
Where can people with lower back pain find heat wrap stockists?
There are a number of stores that sell heat wraps to help with back pain in the UK. On the high street local chemist stores as well as Boots stock heat wraps. Online specialist chemist stores such as Chemist Direct, Lloyds Pharmacy and Express Chemist all sell this product.
Which of these substances has the highest specific heat A aluminum B glass C sand D water?
Water has the highest specific heat of the substances listed. This means it can absorb a lot of heat energy before its temperature rises significantly.
What is the part of speech for insulators?
The word "insulators" functions as a noun. It refers to materials or substances that do not conduct electricity or heat effectively.
What are Substances that absorb light convert it to?
Substances that absorb light convert it to various forms of energy, such as heat or electrical energy. This process is known as photovoltaic effect and is utilized in solar panels to generate electricity from sunlight.
What is the cunductor of heat and electricity of iron?
what is the conductor of heat and electricity of iron
Is heat is a form of electricity?
technically no, electricity is a form of heat though
