Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is
held at a temperature of 100ºC while the other one is kept 0º C. If the two are brought into contact, then, assuming
no heat loss to the environment, the final temperature that they will reach is The potential energy of a point particle is given by the expression V (x) = –αx + β sin (x/γ). A dimensionless
combination of the constant α, β and γ is
