    Energy reconstruction in calorimeter

    Hi guys, I have some general questions and was hoping some of you might be able to answer them. Does anyone know what it means to be "collinear unsafe" and "infrared unstable" when referring to energy reconstruction in calorimeters? Also why do theorist prefer collinear and infrared safe data...

    What Was the Original Mass of the Ice Block?

    I don't even know where to start with this problem, can someone please help. A block of ice at 0 degress C is added to a 150g aluminum calorimeter cup which holds 210g of water at 12 degrees C. If all but 2.0g of ice melt, what was the original mass of the block of ice?

    HHV experiment with bomb calorimeter

    This question refers to a lab that we did for determining the HHV value of bio diesel fuel. We are asked if the experiment was done using a higher initial temperature than the bomb was calibrated for, how would this affect the HHV determined? The room temperature is assumed to be the same in...

    Change in energy = the heat absorbed by the calorimeter and the water?

    I think the answer is d). Am i correct? Because the change in energy equals the heat absorbed by the calorimeter and the water. If not, can you please provide an explanation for your answer. Thanks

    Calculate the heat capacity of this calorimeter

    When using a different calorimeter, and mixing 50 ml of hot water at 65 C with 60 ml of water in the calorimeter at 25 C, the temperture of the calorimeter increased by 5.5 C. Calculate the heat capacity of this calorimeter. Is this a better or worse calorimeter than the one used in the sample...
