20\,\text{g}

of steam at

100\,^{\circ}\text{C}

is passed into

200\,\text{g}

of water contained in a glass calorimeter of mass

50\,\text{g}

at an initial temperature of

25\,^{\circ}\text{C}

. Neglecting heat exchange with the surroundings, calculate the final temperature of the system. Given: • Specific heat capacity of water

= 4.2\times10^{3}\,\text{J kg}^{-1}\,\text{K}^{-1}

• Specific heat capacity of glass

= 8.4\times10^{2}\,\text{J kg}^{-1}\,\text{K}^{-1}

• Latent heat of vaporisation of water

= 2.26\times10^{6}\,\text{J kg}^{-1}
