Answer 1

The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, \lambda, or \kappa. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.

Answer 2

Answer:

There is a quadrilateral shaped field in a village whose one pair of opposite sides is parallel. Guess the shape of the field and calculate its area if the length of parallel sides of field is 14 cm and 6 cm and perpendicular distance between them is 5 cm.
