*starts in classroom* yesenia: alright class today we're going to learn how to calculate the number of calories per gram in a bbq chip and compare it to the actual nutrition label.
jacob: yay im so excited!! james: lets get started
yesenia: " okay we are going to use a beaker of water and burn the chip underneath we will see how the heat from the chip affects the temperature of the water" we need to record the inital temperature of the water and volume of the water.
jacob: the initial volume of the water in 100ml. james: and the initial temperature is 20 degrees celcius & the chip weighs 1.50g. yesenia : perfect now we need to calculate heat gained by h20 , so we take the chip mass and subtract the mass of chip burned so 1.50-0.05 which is 1.45g. now tome for caclulations.
jacob: are we going to use the equation q=mc(delta)t? james : duh jacob what else would we use?
