Steam is passed into 22 g of water at 20^o. The mass of water that will be present when the water acquires a temperature of 90^oC (Latent heat of steam is 540 cal/g) is

The graph AB shown in figure is a plot of temperature of a body in degree celsius and degree Fahrenheit. Then,

The graph shows the variation of temperature (T) of one kilogram of a material with the heat (H) supplied to it. At O, the substances is in solid state. From the graph, we can conclude that

A block of ice at –10^oC is slowly heated and converted to steam at 100^oC. Which of the following curves represents the phenomenon qualitatively?

The portion AB of the indicator diagram representing the state of matter denotes

The figure given below shows the cooling curve of pure wax material after heating. It cools from A and B and solidifies along BD. If L and C are respectively values of latent heat and the specific heat of the liquid wax, the ratio L/C is

A solid substances is at 30^oC. To this substance heat energy is supplied at a constant rate. Then, temperature versus time graph is as shown in the figure. The substance in liquid state for the portion (of the graph) is

The variation of density of water with temperature is represented by the

If a graph is plotted taking the temperature in Fahrenheit along Y–axis and the corresponding temperature in Celsius along the X–axis, it will be a straight line

Which of the curves in figure represents the relation between Celsius and Fahrenheit temperatures?
