    The graph below shows the result of an investigation in which an initially solid specimen of nitrogen absorbs heat a constant rate. Nitrogen melts at 63 K and the specific heat capacity of solid nitrogen is 1.6 kJ kg^-1 K^-1.

    a) Calculate the specific latent heat of fusion of nitrogen.
    b) Calculate the specific heat capacity for liquid nitrogen

    The melting nitrogen absorbs heat for 240 seconds at the same rate it was doing as the solid heated up, at this point it is all melted since it starts to warm.

    In 160 seconds it heated 10 degrees with a shc of 1.6 whic will let you work out the mass.

    Once you gave the mass, you can multiply up to find the latent heat for nitrogen.

    The gradient of the slopes allows you to work out how much change in temperature you are getting per joule of energy per kg for the shc of liquid nitrogen.
