4) Define the detector based on magnetic compass.
5) Write a application of electrolysis
Answers
Answer:
1) Petroleum is a naturally occurring complex mixture made up predominantly of organic carbon and hydrogen compounds. It also frequently contains significant amounts of nitrogen, sulfur and oxygen together with smaller quantities of nickel, vanadium and other elements.

2) Liquid and gaseous fuels do not leave any residue after burning. ... Liquid and gaseous fuels produce little or no smoke, whereas most of the solid fuels burn with smoke. 6. Liquid and gaseous fuels have relatively low ignition temperature and hence they burn more easily than solid fuels.
3) Electric current may also be carried by ions in an electrolyte or by both ions and electrons like that in a plasma. For monitoring purposes, an AC current sensor can be used to detect electric current and measure it in amperes using a device called an ammeter.
4) a device that is used to find direction by means of a needle that always points north.
5) Applications of Electrolysis
(i) Production of hydrogen by electrolysis of water. (ii) Manufacture of heavy water . (iii) The metals like K, Mg, Al, etc., are obtained by electrolysis of fused electrolytes. (iv) Non-metals like hydrogen, fluorine, chlorine are obtained by electrolysis.
