What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.
How do electrical companies store electricity?
They don't. Power is always being used somewhere, and the electrical systems are connected all over the country.AnswerThere is no direct means of storing electrical energy, Energy companies generate energy to meet the demand placed on it by the load being supplied. If the load goes up, then more energy is generated to meet that load; if the load goes down, then less energy is generated. The energy generated does not exceed the load.Energy can be stored indirectly. For example, hydroelectric power systems rely on the water stored behind dams in order to generate electrical energy so, in that sense, energy is indeed being stored.
How come magnets aren't a source of unlimited energy when the force between them is constant?
When standing in a bus-queue with a constant force between my feet and the ground there is no obvious source of energy, unlimited or finite. If I fall onto my neighbours shopping bag, crushing her eggs, some energy is supplied but it is limited. As soon as my body is flat on the ground there is no more energy to be had. If two magnets are held an inch apart, north opposite south and south opposite north, there will be an attractive force. There is potential energy here, and if the magnets are allowed to come together work will be done, energy supplied. This is not unlimited energy; it stops being available as soon as the magnets jam up against each other. Of course, you can recharge that energy by pulling the magnets apart, but then your muscles will have supplied the energy. The motto of physics, and of the entire universe, is TANSTAAFL. There ain't no such thing as a free lunch.
How does a Bohr model illustrate electron placement within an atom?
electron travel around the neucleus in different (fixed) energy levels
What should be handled directly after being over a Bunsen burner?
the iron ring, the wire mesh over the ring, the beaker or whatever else was being heated. There are special tongs for most types of glassware or porcelain objects that are heated over a Bunsen burner.
How do you know that there is energy in an electric motor?
If there is energy in an electric motor (electricity is being supplied to it). it will be turing/running. When there is no energy in it (being supplied to it) it will stop.
What is the name of electrons before energy is supplied to them?
Prior to energy being supplied to them, the electrons are named neutrons. A neutron normally breaks into a proton and an electron.
What type of energy is given off by a stove is it light and heat energy or heat energy only?
Well, we're sure that there's heat energy. If you can see the gas flame of the burner, or the red glow of the electric burner element, then there has to be light energy being radiated too.

Why doesn't cold water make a hot burner cold?
Heat is a form of energy and due to the principal of thermodynamic equilibrium, will constantly seek a state of equilibrium. The reason a hot burner does not become cold is because as the energy is transferred to the cold water more energy is being put into the burner through either electricity or gas. If there was no source of energy to the burner, then the cold water would cool down the hot burner, though the cold water would also heat up in the process, to the point where both are at room temperature.
What is France's primary source of power?
France is mainly supplied by electrical energy, 80 % of this electricity being produced by nuclear powerplants.
A machine has an effciency of 91 percent if the energy is supplied to the machine is 4000 watts what is the amount being used for work?
3640 Watts.
A machine has an efficiency of 91 percent If the energy supplied to the machine is 4000 watts what is the amount being used for work?
4,091 watts
When heat is being supplied to a solid then what does the heat energy do to the particles of solid?
Adding heat energy will usually increase the temperature. At the level of the individual particles, the particles will vibrate faster.
What are the advantages disadvantages of thermador cooktops?
When using a thermador cooktop, only the pot or pan used is being heated and not the burner. When using electricity or gas, the burner gets hot as well as the pot or pan being used. Thus, thermador cooktops are more energy efficient by cooking faster and cooling down faster.
When temperature does not increase and there is a constant supply of energy where does the energy go?
One possibility is that the temperature is absorbed by a change of phase - for example, when ice melts. This is an increase in potential energy. Of course, it is also possible for energy to drain off (the object cools down while energy is being supplied).
A machine has an efficiency of 91 percent If the energy supplied to the machine is watts what is the amount being used for work?
If the efficiency is 91%, then work = 0.91 times watts
