Please answer thx
Dear student,
Please find below the answer:
E. 1. The correct option is (a).
Conduction is the mode of flow of heat from one point to another inside a medium without any actual flow of matter. It takes place in solids. Example- When the iron rod is heated from one end then the other gets heat due to conduction of heat.
2. The correct option is (c).
Conductors are the substances that conduct electricity through them while Insulators are the substances that do not conduct electricity. Iron, aluminium and copper are conductors while wood is an insulator.
3. The correct option is (a).
The temperature at which liquid changes into solid at atmospheric pressure is called the freezing point. The freezing point of water is 00 C.
4. The correct option is (a).
The upper fixed point is the temperature at which pure water boils at sea level. For pure water, it is 1000 C.
5. The correct option is (b).
Land and sea breeze occurs due to convection currents.
Please post rest of the questions in a separate thread.
Regards.
