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 by them for complete fusion is

Which of the substances A, B or C has the highest specific heat ? The temperature vs time graph is shown

The graph signifies

A student takes 50gm wax (specific heat = 0.6 kcal/kg°C) and heats it till it boils. The graph between temperature and time is as follows. Heat supplied to the wax per minute and boiling point are respectively

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

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

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

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

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

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