The oxidation of 0.4362 g of naphthalene (C10H8) caused a temperature rise of 1.707 K in an adiabatic bomb calorimeter. The heat capacity of the calorimeter, the final temperature was 298 K, water was 10 290 J/K, and the heat capacity of the produ
The particle consists of a speed of 3 m/s on surface A. A non-conservative outside force is exerted to the particle and it moves to the surface B, arriving there having a speed of 4 m/s. Determine how much work is done by the outside force in movi
In principle, anytime someone jumps up, the earth moves in the opposite direction. To observe why we are unaware of this motion, compute the recoil speed of the earth if a 73.0 kg person jumps upward at a speed of around 1.50 m/s.
When 21.45 g of potassium nitrate, KNO3, was dissolved in the water in a calorimeter, the temperature fell from the 25.00*C to14.14*C. What is the ΔH for the solution process?
