The variation of density of water with temperature is represented by the
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
$2\;gm$ of steam condenses when passed through $40gm$ of water initially at $25^oC.$ The condensation of steam raises the temperature of water to $54.3^oC.$ What is the latent heat of steam ........... $cal/g$
At temperatures close to $0\ K$ , the heat capacity $C$ of a certain solid is related to its temperature $T$ by the equation $C = aT^3$ , where a is a constant characteristic of the solid. Heat is supplied to the solid at a steady rate. Which graph best represents the variation of its temperature $T$ with time $t$ ?
The portion $A B$ of the curve representing the state of matter denotes
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:
