A lead bullet is fired at a wooden plank. At what speed must bullet travel to melt on impact, if its initial temperature is 25oC and the heating of the plank is neglected.
The temperature of the solution drops by 22.4 degrees Celsius. If the specific heat of the solution is 4.18J/g degrees C, calculate the enthalpy of the solution of ammonium nitrate.
Explain why selectivity in isocratic HPLC system ideally should not depend on eluent composition. Use thermodynamic derivation to support your explanation.
