02. Biomass

Plant or animal materials which can be used as a fuel, are known as “biomass”

Example for biomass

Coconut shells, coal, rotten vegetables, hay, saw dust, rice bran, rotten food materials and agricultural waste

Activity 4.3 Let's make a saw dust stove or “kudu lipa”/ "thool aduppu" https://youtu.be/E7IKSK-FKOE?t=2341

​Do you know?

Temperature
Thermometers are used to measure the temperature. Temperature is measured in Celcius or Fahrenheit. Temperature is measured in Celcius (0 C) in day-to-day applications.

Standard body temperature lies between 36 ⁰C to 37 ⁰C (97 to 98 F)
Standard room temperature is 32 ⁰C
