Does pure water conduct electricity? If not, what can we do to make it conducting?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans.<\/strong> No. Pure water does not conduct electricity. This is because pure water is devoid of any salts. Pure water can conduct electricity when a pinch of common salt is added to it, as salt solution is conducting in nature.<\/p>\n<hr \/>\n<h3><span class=\"ez-toc-section\" id=\"7_In_case_of_fire_before_the_firemen_use_the_water_hoses_they_shut_off_the_main_electric_supply_for_the_area_Explain_why_they_do_this\"><\/span><strong>7. In case of fire, before the firemen use the water hoses, they shut off the main electric supply for the area. Explain why they do this.<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans. <\/strong>Water may conduct electricity. If the electrical supply for the area is not shut off and water is poured over electrical appliances, then electricity may pass through water and harm the firemen. That is why, in case of a fire, the firemen shut off the main electrical supply for the area before they use the water hoses.<\/p>\n<hr \/>\n<h3><span class=\"ez-toc-section\" id=\"8_A_child_staying_in_a_coastal_region_tests_the_drinking_water_and_also_the_seawater_with_his_tester_He_finds_that_the_compass_needle_deflects_more_in_the_case_of_seawater_Can_you_explain_the_reason\"><\/span><strong>8. A child staying in a coastal region tests the drinking water and also the seawater with his tester. He finds that the compass needle deflects more in the case of seawater. Can you explain the reason?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans. <\/strong>The water used to extinguish fire, have lot of minerals and dissolved salt, which make it conducting. Before throwing water into the burning houses and the mains of electricity of the area is shut off because then the water may conduct huge current and firemen get electric shock.<\/p>\n<hr \/>\n<h3><span class=\"ez-toc-section\" id=\"9_Is_it_safe_for_the_electrician_to_carry_out_electrical_repairs_outdoors_during_heavy_rain_pour_Explain\"><\/span><strong>9. Is it safe for the electrician to carry out electrical repairs outdoors during heavy rain pour? Explain.<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans. <\/strong>The impure water is conductor of electricity. Sea water contains more impurity than drinking water found in the coastal region. Therefore, sea water conducts more electricity than drinking water. That is why, compass needle deflects more in case of sea water.<\/p>\n<hr \/>\n<h3><span class=\"ez-toc-section\" id=\"10_Paheli_had_heard_that_rainwater_is_as_good_as_distilled_water_So_she_collected_some_rainwater_in_a_clean_glass_tumbler_and_tested_it_using_a_tester_To_her_surprise_she_found_that_the_compass_needle_showed_deflection_What_could_be_the_reason\"><\/span><strong>10. Paheli had heard that rainwater is as good as distilled water. So, she collected some rainwater in a clean glass tumbler and tested it using a tester. To her surprise she found that the compass needle showed deflection. What could be the reason?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans. <\/strong>When it rain heavily, the rain water dissolves many impurities from the atmosphere, which make it impure and very conductive of electricity. The air becomes humid with this water and becomes very conductive. That is why, it is not wise for electrician to do electrical repair work when it rains heavily, because he may get dreadful shock or even gets electric shock.<\/p>\n<hr \/>\n<h3><span class=\"ez-toc-section\" id=\"11_Prepare_a_list_of_objects_around_you_that_are_electroplated\"><\/span><strong>11. Prepare a list of objects around you that are electroplated.<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans. <\/strong>Rain water is, of course, as good as distilled water but, when it passes through atmosphere, it dissolves a lot of dust, dirt and impurities and become conducting. So, when Paheli used a tester, its compass showed deflection.<\/p>\n<p>The objects which are electroplated are:<\/p>\n<p>(i)\u00a0\u00a0 Taps of water connection.<\/p>\n<p>(ii) Parts of bicycle.<\/p>\n<p>(iii) Body of cars, motor cycle and tractors.<\/p>\n<p>(iv) Handles of the doors.<\/p>\n<hr \/>\n<h3><span class=\"ez-toc-section\" id=\"12_The_process_that_you_saw_in_Activity_147_is_used_for_purification_of_copper_A_thin_plate_of_pure_copper_and_a_thick_rod_of_impure_copper_are_used_as_electrodes_Copper_from_impure_rod_is_sought_to_be_transferred_to_the_thin_copper_plate_Which_electrode_should_be_attached_to_the_positive_terminal_of_the_battery_and_why\"><\/span><strong>12. The process that you saw in Activity 14.7 is used for purification of copper. A thin plate of pure copper and a thick rod of impure copper are used as electrodes. Copper from impure rod is sought to be transferred to the thin copper plate. Which electrode should be attached to the positive terminal of the battery and why? <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans. <\/strong>The thick rod of impure copper should be attached to the positive terminal of battery. This is because the free copper of the solution will get deposited on the thin rod and the loss of copper from the solution will be restored from the thick rod to the positive terminal of the battery. Thus, copper from the thick rod could be extracted out.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"NCERT_Solutions_for_Class_8_Science\"><\/span>NCERT Solutions for Class 8 Science<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>NCERT Solutions Class 8 Science PDF (Download) Free from myCBSEguide app and myCBSEguide website.
