Question

There is a cuboid of dimensions $1\times b\times h$ and thermal capacity 'K' units. On doubling the dimensions of the cuboid. Find the thermal capacity.

Answer 1

Thermal capacity=mass$\times$Specific heat

or, Thermal capacity = density$\times$volume$\times$specific heat

Its clear from above equation, if we double the dimension i.e., volume of the cuboid, the thermal capacity gets doubled. hence, new thermal capacity is '2K' units.
