Question

Two identical beakers A and B contain equal volumes of two different liquids at 60° C
each and left to cool down. Liquid in A has density of 8 × 10² kg/m³ and specific heat of 2000 Jkg⁻¹ K⁻¹ while liquid in B has density of 10³ kgm⁻³
and specific heat of 4000Jkg⁻¹ K⁻¹ . Which of the following best describes their temperature versus time graph schematically? (assume the emissivity of both the beakers to be the same)

Answer 1
