Question

Three lawn chairs, one made up of aluminium (heat capacity = 0.90 J/K-g), one of iron (heat capacity = 0.45 J/K-g) and one of tin (heat capacity = 0.60 J/K-g) are painted of the same colour. On a sunny day which chair will be hotter to sit?

Prashant Kotian · Accepted Answer

Correct answer: A. For identical heat exposure, the material with the lowest specific heat capacity undergoes the greatest temperature increase. Iron has the lowest specific heat (0.45 J/K-g) among the options.
