Figure 7
Given that the density of water is 1000 kg/m³, the specific gravity of oil is 0.72 and the
specific gravity of mercury is 13.6, determine the differential height, h.
В.
A substance of mass m¡ at a temperature of 300 K is supplied with 1000 J of energy such
that its temperature increases to 350 K. When the same substance of mass m2 is supplied
with 800J of energy, its temperature changes from 275 K to 305 K.
Determine the ratio of mị to m2.
