WebSpecific heat of Invar is 505 J/g K. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. The intensive properties c v and c p are defined for pure, simple compressible substances as partial derivatives of the internal energy u(T, v) and enthalpy h(T, p) , respectively: WebThe thermal resistance for heat conduction through a spherical wall is a) (r 2-r 1)/2πkr 1 r 2 b) (r 2-r 1)/3πkr 1 r 2 c) (r 2-r 1)/πkr 1 r 2 d) (r 2-r 1)/4πkr 1 r 2 View Answer. Answer: d …
WebHeat loss by conduction is negligible. Heat loss by convection (i.e. due to air currents or wind) will be dependent upon the geographic location of the conductor 100. A conductor 100 may be deployed in a hot region of the world such as Southern USA, the Middle East or Australia. Winds in non-coastal regions may be relatively light and hence ...
