A small quantity, mass $m$ , of water at a temperature $\theta $ (in $^oC$ ) is poured on to a large mass $M$ of ice which is at its melting point. If $c$ is the specific heat of water and $L$ the latent heat of fusion of ice, then the mass of ice melted is given by
$\frac{{ML}}{{mc\theta }}$
$\frac{{mc\theta }}{{ML}}$
$\frac{{Mc\theta }}{{L}}$
$\frac{{mc\theta }}{{L}}$
The coefficient of apparent expansion of mercury in a glass vessel is $153 × 10^{-6}{°C^{-1}}$ and in a steel vessel is $144 × 10^{-6}{°C^{-1}}$. If $\alpha$ for steel is $12 × 10^{-6}{°C^{-1}}$, then that of glass is
A solid cube having certain fixed melting and boiling points takes heat from some source. The variation of temperature $\theta$ of the cube with the heat supplied $Q$ is shown in the adjoining graph. The portion $BC$ of the graph represents the conversion of
A block of ice at $-10\,^oC$ is slowly heated and converted to steam at $100\,^oC.$ Which of the following curves represent the phenomenon qualitatively ?
‘Stem Correction’ in platinum resistance thermometers are eliminated by the use of
The graph $AB$ shown in figure is a plot of temperature of a body in degree Celsius and degree Fahrenheit. Then
