1 00:00:01,000 --> 00:00:14,300 Okay, we are going to do page 76 and 77, but before, we are going to review nuclear energy, alright? Nuclear energy, okay? 2 00:00:15,640 --> 00:00:24,199 Well, let me know what you did before. So, uranium, what type of substance is it? Do you know? 3 00:00:26,000 --> 00:00:27,940 Uranium. What do you think is uranium? 4 00:00:27,940 --> 00:00:34,939 Me! It's a radio tip. Radio tip. Good. Very good. 5 00:00:34,939 --> 00:00:42,939 Remember, we're going to do pages 76 and 77, but now these are pages 70... 6 00:00:42,939 --> 00:00:46,939 This is pages 74. This is pages 74, okay? 7 00:00:46,939 --> 00:00:51,939 Well, please, if you're talking and whispering and cheating, 8 00:00:51,939 --> 00:00:56,939 this is really hard for me to talk to, thank you. I appreciate it. 9 00:00:56,939 --> 00:00:59,679 uranium. So we're talking about 10 00:00:59,679 --> 00:01:00,219 uranium. 11 00:01:02,460 --> 00:01:03,659 It's a 12 00:01:03,659 --> 00:01:04,079 radioactive 13 00:01:04,079 --> 00:01:07,700 system, right? 14 00:01:08,439 --> 00:01:09,579 It's a radioactive 15 00:01:09,579 --> 00:01:10,239 system. 16 00:01:11,560 --> 00:01:12,980 Radioactive, sorry. 17 00:01:13,439 --> 00:01:15,659 Radioactive system. 18 00:01:16,560 --> 00:01:16,900 Alright? 19 00:01:18,120 --> 00:01:19,799 Alright. Here we are. 20 00:01:20,620 --> 00:01:21,739 It is used in 21 00:01:21,739 --> 00:01:22,719 nuclear power. 22 00:01:23,939 --> 00:01:25,420 It's used 23 00:01:25,420 --> 00:01:28,980 in nuclear 24 00:01:28,980 --> 00:01:31,000 power. 25 00:01:33,060 --> 00:01:36,480 No problem. 26 00:01:39,680 --> 00:01:40,560 You are very welcome. 27 00:01:43,060 --> 00:01:45,760 It is used in nuclear power stations. 28 00:01:46,079 --> 00:01:49,159 So remember, don't pronounce it 29 00:01:49,159 --> 00:01:52,959 like uranium, don't pronounce it like radioactive, don't say 30 00:01:52,959 --> 00:02:09,099 substance under say nuclear don't say a stadium say uranium radioactive substance nuclear station 31 00:02:09,099 --> 00:02:21,819 it's water to produce a stem right so this is the nuclear energy nuclear energy nuclear energy 32 00:02:21,819 --> 00:02:36,819 nuclear energy. Well, nuclear energy has advantages and disadvantages. So we're going to talk about the advantages and the disadvantages. 33 00:02:36,819 --> 00:02:43,819 Disadvantages. Remember we don't say alvantajes or disadvantages. No. Disadvantages. 34 00:02:43,819 --> 00:02:48,819 Disadvantages. 35 00:02:51,819 --> 00:02:56,819 More things. We are, we should say, tributary. 36 00:02:56,819 --> 00:02:59,819 Fuentes. They are our tributary. Remember. 37 00:02:59,819 --> 00:03:05,819 Another thing that we usually pronounce badly is fangales. Alright? 38 00:03:05,819 --> 00:03:12,680 eco ecosystems we don't say ecosystem we say ecosystems all right this is no we 39 00:03:12,680 --> 00:03:26,800 must advantages advantages the production of nuclear energy doesn't 40 00:03:26,800 --> 00:03:35,800 It does not pollute the atmosphere. It does not pollute the atmosphere. 41 00:03:35,800 --> 00:03:38,800 It is an advantage. 42 00:03:38,800 --> 00:03:42,800 Nuclear power plants are very expensive to produce. 43 00:03:42,800 --> 00:03:44,800 We are talking about advantages. 44 00:03:44,800 --> 00:03:50,800 Nuclear energy is cheap to produce. It is cheap to produce. 45 00:03:50,800 --> 00:03:55,800 It is cheap to produce. 46 00:03:55,800 --> 00:04:02,680 so you understand this right it's not expensive so the advantages that we can do very small amounts 47 00:04:02,680 --> 00:04:10,680 of uranium produce large amounts so it's efficient efficient what it means efficient 48 00:04:10,680 --> 00:04:18,199 it's not very expensive with a small amount we produce a lot okay and efficient ecfi we need 49 00:04:18,199 --> 00:04:22,360 a lot of things to do something and efficient it could be for example to do an strawberry 50 00:04:22,360 --> 00:04:31,250 Ok, to do a strawberry, to do a strawberry milkshake, ok? 51 00:04:31,250 --> 00:04:33,250 Because the strawberry milkshake... 52 00:04:37,250 --> 00:04:38,610 Stop it! No!
