Please show each step: Tony burns a 0.6 gram peanut submerged in 50 grams of water, which increases its temperature from 22 to 50 ° C. a) Assuming an efficiency of 40%, calculate the nutritional value of the peanut. b) Demonstrate that the nutritional value in calories per gram.

Answer 1

nutritional value=heat/mass

heat=masswater*specificheatwater*changintemp

so divide the heat in the water by .4, and you have the heat of the nut. Solve for nutritional value.
