Explanation:

Mud houses are cold in summer and hot in winter. Air gaps in mud helps to remain cold in summers and hot in winter.

1. Answer. Yes, it can pass easily. As radiant heat is a type of heat radiation, it does not require any material medium in its surroundings to transfer the heat from one hot object to another cold object. It radiates its heat so it can very easily pass in air as well as vaccum also.

2. Radiation is the fastest mode of heat transfer while conduction is the slowest mode of heat transfer. Radiation is defined as the mode of heat transfer which takes place through the vacuum and doesn't require any physical medium. Sunlight is an example of radiation.

3. Air is an insulator. This is because air is a gaseous substance and gaseous substances are poor conductors of heat.

4. A thermometer is a tool that measures temperature — how hot or cold something is.Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward. Thermometers measure temperatures in degrees, according to either the Celsius or Fahrenheit system.

Thermometer measures the temperature of body

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.
