What is vapourization ? What is normal boiling point ?
A closed bottle containing water at $30°C$ is carried to the moon in a space-ship. If it is placed on the surface of the moon, what will happen to the water as soon as the lid is opened
Explain the process of change in state of matter by heating or cooling it.
A solid material is supplied with heat at constant rate and the temperature of the material changes as shown below. From the graph, the false conclusion drawn is:
When the pressure on water is increased the boiling temperature of water as compared to $100°C$ will be
A given mass $m$ of a hypothetical solid is supplied with heat continuously at a constant rate and the graph shown in the adjacent figure is plotted. If $L_f$ and $L_v$ are latent heats of fusion and latent heats of vaporization and $S_l$ and $S_s$ are specific heats of liquid and solid respectively. It can be concluded that
