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
The portion $AB$ of the indicator diagram representing the state of matter denotes
when a man eats $100\,g$ of ice in a minutes, how much power will he get ? The latent heat of ice is $80\,cal/g$.
A closed bottle containing water at $30^{\circ} C$ is open on the surface of the moon. Then,
If liquefied oxygen at $1$ atmospheric pressure is heated from $50\, K$ to $300\, K$ by supplying heat at constant rate. The graph of temperature vs time will be
