Xenon gas is released during a certain chemical reaction and pushes back the atmosphere with a change in volume of the vessel (it has a movable piston) from 2 to 20 Liters. Calculate the work done by this release of gas.
The density of solutions are assumed to be the same as water. If the density of all 3 solutions was actually 1.1 g/mL, how would the heat of the reaction be affected?
In an experiment using a temperature probe, is there a way to estimate the heat absorbed by the temperature probe? Explain how.
what effect will that have on the delta T values when the initial value is measured with the thermometer and the latter is measured with the temperature probe? How will this affect the calculated change in heat of that substance?
