One example of bad thermal insulator is

  • potassium
  • paper
  • cork
  • wool

The color and texture of a poor reflector of radiant heat is

  • black and shiny
  • black and dull
  • white and shiny
  • white and dull

The insulation reduces the amount of heat

  • leaving the house
  • entering the house
  • transferring the chamber
  • releasing the chamber

In fire fighting another use of thermal imaging camera is

  • spotting source of fire
  • spotting people in the fire
  • identifying flammable objects
  • identifying wood and steel

The stopper is made up of

  • metal
  • transition metal
  • good insulator of heat
  • poor insulator of heat

Majority of the people wear white or light colored clothes in summer, because light colors

  • s
  • reflect less heat
  • reflect more heat
  • transfer less heat

"Thermos" was invented by a

  • French scientist
  • Spanish scientist
  • American scientist
  • Scottish scientist

Fire fighters use thermal image cameras to identify

  • the spread of fire
  • the source of fire
  • the heat released by fire
  • the temperature of fire

Like light and heat, radio waves can also travel through

  • water
  • solids
  • sand
  • vacuum
