A closed bottle containing water at $30^{\circ} C$ is open on the surface of the moon. Then,
the water will boil
the water will come out as a spherical ball
the water will freeze
the water will decompose into hydrogen and oxygen
Why skating is possible on ice ?
Explain the process of melting of ice with explanation of freezing, melting and melting point.
The point on the pressure temperature phase diagram where all the phases co-exist is called
Liquid oxygen at $50\ K$ is heated to $300\ K$ at constant pressure of $1\ atm$. The rate of heating is constant which of the following graphs represents the variation of temperature with time
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
