    Given that,

    Mass of water = 1.26 kg

    Latent heat of vaporization of water L=2.26\times10^{6}\ J/kg

    We need to calculate the latent heat

    Using formula of latent heat

    Q=mL

    Where, Q = energy

    m = mass

    L = latent heat of vaporization

    Put the value into the formula

    Q=1.26\times2.26\times10^{6}

    Q=2847600\ J

    Q=2.84\times10^{6}\ J

    The temperature changes liquid to steam.

    So, The temperature will be increases.

    Hence, The latent heat is 2.84\times10^{6}\ J and temperature increases.
