When a block of iron floats in mercury at 0°C fraction ky of its volume is submerged, while at the temperature 60 °C a fraction ky is seen to be submerged. If the coefficient of volume expansion of iron is ype and that of
mercury is Yn, then the ratio kr/kz can be expressed as
​

Answer 1

Answer:

When a block of iron in mercury at 0∘C, fraction K1of its volume is submerged, while at the temperature 60∘C, a fraction K2 is seen to be submerged. If the coefficient of volume expansion of iron is γFe and that of mercury is γHg, then the ratio (K1)/(K2) can be expressed as.
