6. An icy wind whistled and scraped against the once towering trees, laden heavy with snow
and bowed and broken under the weight. Two moons had passed since the pale winter sun
had cast its last desperate offerings of warmth onto the wilderness. Mr. Martel trudged back
to the cave, his hand clasped firmly around the tattered rags he called a coat. Snow walled
against him, his legs burning from exertion. The bitter cold stabbed at his flesh and the
mortal curtain closed around his eyes. The bundle of twigs he bore scratched at his arms,
skin dry from the cold and clawing wind. Fully dephlogisticated, twigs can output 145.4 kJ of
energy. To survive, Mr. Martel needs to drink 1.6 L of water (water, 1 g = 1 mL) at 10°C. The
snow is at -24 °C. Do the twigs provide enough energy to melt and warm 1.6 L of snow? Will
Mr. Martel survive?
