ENERGY VALUE IN FOOD SAMPLE

State the manipulated variable for this experiment.

• type of nuts

• volume of distilled water

• increase in the temperature of the water

• the mass of nuts

State the responsing variable for this experiment

• initial temperature of the water

• increase in the temperature of the water

• final temperature of the water

State the hypothesis for this experiment

• the higher the temperature of the water, the higher the energy value

• cashew nut has the higher energy value compare to peanut

• Different food sample has different value of energy

• the increase in temperature of the water will affect the energy value in food sample

state the constant variable for this experiment

• type of nuts

• initial temperature of water

• volume of water

what form of energy is released when the peanut burns ?
