Answer:
She can consider using agricultural waste or dried dung.
Explanation:
No doubt, biomass has become a crucial source of energy to the society, with almost 90% of the households in rural area now relying on biomass for energy. Biomass has become a great option for household heating and cooking. It is locally available and abundant. It is a clean type of fuel, unlike fossil fuels and it somehow helps in cleaning our environment as it traps carbondioxide. Some common types of biomass include dried dung, agricultural waste, or even charcoal.
Answer:
(a) Initial volume will be 7.62 L
(b) Final temperature will be 303.85 K
Explanation:
We have given one mole of ideal gas done 3000 J
So work done W = 3000 J
Let initial volume is 
and initial pressure 
( As pressure is constant )
Final volume 
= 0.025 
Number of moles n = 1
(B) From ideal gas of equation we know that 
So 
T = 303.85 Kelvin
(B) For isothermal process work done is equal to
So initial volume will be 7.62 L
I would say D) melting point.
