Problem

If you add 1.33 MJ of heat to 500 g of water at

50^{\circ}\text{C}

in a sealed container, what is the final temperature of the steam? The latent heat of vaporization of water is

22.6 \times 10^5 \text{ J/kg}

, the specific heat of steam is

2010 \text{ J/kg} \cdot \text{K}

, and the specific heat of water is

4186 \text{ J/kg} \cdot \text{K}

. (a)

100^{\circ}\text{C}

(b)

112^{\circ}\text{C}

(c)

123^{\circ}\text{C}

(d)

195^{\circ}\text{C}
