Is Making silver jewelry a chemical change?
No, if your starting point is sliver wire or bar, the process making jewelry is mechanical, the raw material is heated and forged into jewelry, there is no chemical change.
What is a chemical reaction that happens when a hot air balloon flies?
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
Is adding water to heated copper sulfate crystals chemical or physical?
chemical
What is the chemical equation of heated iron andsulfur?
chemical equation of heated iron and sulfur is as follows. FeS can be obtained by the heating of iron and sulfur:Fe + S → FeS.
Why is a copper wire in a closed circuit does not get heated but a nichrome does?
this is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .
What energy transformation takes place in an engine?
In steam and combustion engines, thermal energy is changed to mechanical energy. Either heated gas or heated fluid is created that exerts force to turn the engine. In combustion engines, chemical energy becomes thermal energy which becomes mechanical energy. In electrical engines (motors), electrical energy is changed to mechanical energy by the manipulation of magnetic fields.
How do you convert heat energy into mechanical energy?
In a power plant, water is heated and evapourates, it flows through a turbine and turns it - this is mechanical energy.
Can a person lifting a weight be chemical energy to mechanical energy or a dark light bulb starting to glow or food being heated in an oven or a ball rolling down a hill?
Lifting wieghts
What type of energy is produced when a heated chemical glows?
Photons are emitted (light energy) and infrared energy.
What is chemical energy and how is energy released?
chemical energy is energy found in substances. energy is never lost or gained (remember that) . you can measure the energy and release energy by heating substances. This way energy is released when the compounds heated are broken down.
When a pure substance is heated or cooled but does not change state the energy as heat is the what?
chemical change
What does the energy stored in the kernels of corn change into when the energy as the kernels move inside the popcorn popper?
Corn does not pop due to stored energy. There is moisture inside the hard kernel of corn. When heated, the heat changes that to steam, which expands, and blows open the kernel. Heat is transformed to mechanical energy- but the heat energy comes from outside, not inside.
What type of engine converts Thermal energy to thermal energy?
A car's energy source is the chemical energy of it's fuel. This energy is liberated as thermal energy in the pressurized heated gas products. The expansion of the gases in the engine's cylinders, now mechanical energy, is directed toward the mechanical devices that will direct this energy to the rotation of the wheels. A car's engine is a heat engine. It transforms thermal energy in the form of heat to mechanical energy. But according to thermodynamics 2nd law, it cannot transform all of the heat to mechanical energy, just some amount. The rest of the heat has to be dissipated to a low temperature heat deposit (or heat sink). That's why a car needs a heat dissipating system (the radiator).
Is Making silver jewelry a chemical change?
No, if your starting point is sliver wire or bar, the process making jewelry is mechanical, the raw material is heated and forged into jewelry, there is no chemical change.
Is a candle heated by chemical energy?
No; the process only takes place the other way around. The chemical energy in the wax is converted in an exothermic reaction (combustion) to "free" energy, which goes into the air around (heat).
What type of energy does a furnace use?
A furnace can be heated by fossil fuels like coal, coke, or natural gas, which is chemical energy or it can be electric.
What energy can be converted to what energy when mercury oxide is heated please help fast?
Metallic mercury has chemical potential energy, since it can combine with oxygen in an exothermic reaction, therefore, by driving out the oxygen with heat, you are converting heat energy to chemical potential energy.
