A 2g sample of biomass was fully combusted in a calorimeter. The volume of water in the calorimeter was 100cm^3. The increase in temperature recorded was 15.7oC. 4.18J of energy are needed to increase the temperature of 1cm^3 of water by 1oC. Use this information to calculate the heat energy released in KJ per g of biomass. Show your working. (2 marks) - correct answears100cm^3/1000 = 0.1kg 0.1x4.18x15.7= 6.56/2= 3.28KJ/g A scientist calculated the surface area of a large number of frog...
