A 455-g piece of copper tubing is heated to 89.5 Celcius and placed in an insulated vessel containing 159g of water at 22.8 degrees Celcius. Assuming no loss of water and a heat capacity of 10.0 J/K for the vessel, what is the final temerature? (c of copper =0.387 J/g*K)
Determine What would be the total volume in the graduated cylinder if density of Ag= 10.5 g/mL.?
The work function for mercury is equivalent to 435 kj/mol photons. When light of 205nm strikes a mercury surface,the kinetic energy is 2.47x10^-19 J/photon. What is the velocity of the ejected electrons in m/s?
