216 -- In a bomb calorimeter containing $2\text{ kg}$ of water, a mixture of $0.5$ mol of methane gas and $2$ mol of oxygen gas is burned $(\Delta E_{\text{combustion}} = -890\text{ kJ.mol}^{-1})$. The temperature inside the calorimeter increases by approximately how many degrees Celsius? (The heat absorbed by the calorimeter body and gases is neglected, and the specific heat capacity of water is $4.2\text{ J.g}^{-1}.^\circ\text{C}^{-1}$.)
