The corfficient of linear expansion for a certain metal varies with temperature as `alpha(T)`. If `L_0` is the initial elgnth of the metal and the temperature of metal is changed from `T_0` to `T(T_0gtT)`, then

The variation of length of two metal rods A and B with change in temperature is shown in Fig. the coefficient of linear expansion alpha_A for the metal A and the temperature T will be

n moles of an ideal gas undergo a process in which the temperature changes with volume as T=kv^(2) . The work done by the gas as the temperature changes from T_(0) to 4T_(0) is

Each side of a box made of metal sheet in cubic shape is 'a' at room temperature 'T', the coefficient of linear expansion of the metal sheet is ' alpha '. The metal sheet is heated uniformly, by a small temperature Delta T , so that its new temperature is T + Delta T . Calculate the increase in the volume of the metal box.

The radius of a metal sphere at room temperature T is R, and the coefficient of linear expansion of the metal is alpha . The sphere is heated a little by a temperature DeltaT so that its new temperature is T+DeltaT . The increase in the volume of the sphere is approsimately.
