why wood is used in calorimeter
Answers
Answer:
Many softening measurements have used water-saturated wood samples to ensure that their moisture conditions remain constant during the tests. The mechanical properties of wood are highly sensitive to the moisture content in the microstructure since water acts as a plasticizer.
Explanation:
Answer:
CALORIMETER
▶Calorimeter have a cylinder vessel which is made up of thin sheet of copper .
▶The outer and inner surfaces that are alsilo made up of copper are polished to reduce loss of heat by radiation
▶To provide insulation its places in a wooden jacket and the space between wooden jacket and copper sheet is filled with wool or cotton to avoid heat by conduction.
▶Its covered with lid with two hole, one for thermometer and one for stirrer. is made up of wood to prevent heat loss by convection.
◼Copper is used in making its vessel because :-
▶Copper have low specific heat capacity , so takes up small amount of heat from substance.
▶It easily acquires temperature of the substance added as its a good conductor of heat and electricity.
