Answer:
1.Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
2.Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).
3.the temperature measured in the digital thermometer are more exact than the temperature measured in the mercury thermometer. and also if mercury thermometer breaks then mercury which is very toxic comes out and may create problems.
4.In places of hot climate, it is advised that the outer walls of house be painted white because white colour does not absorb any heat radiation from the sun which keep inside cool even if there is hot climate outside the house.
5.Air is trapped in the space between two thin blankets. Since air is an insulator of heat, it prevents the escape of body heat. That is why two thin blankets are usually warmer than one thick blanket.
