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 J kg–1 K–1 while liquid in B has density
of 103 kg m–3 and specific heat of
4000 J kg–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)
