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
The variation of density of water with temperature is represented by the
Heat is supplied to a certain homogenous sample of matter, at a uniform rate. Its temperature is plotted against time, as shown. Which of the following conclusions can be drawn
Which of the substances $A, B$ or $C$ has the highest specific heat $?$ The temperature vs time graph is shown
Two substances $A$ and $B$ of equal mass m are heated at uniform rate of $6\, cal s^{-1}$ under similar conditions. $A$ graph between temperature and time is shown in figure. Ratio of heat absorbed ${H_A}/{H_B}$ by them for complete fusion is
A metallic ball and highly stretched spring are made of the same material and have the same mass. They are heated so that they melt, the latent heat required
