High-altitude mountain climbers do not eat snow, but always melt it first with a stove.
A) To see why, calculate the energy absorbed from your body if you eat 0.60 kg of -7 ∘C snow which your body warms to body temperature of 37∘C.
B) Calculate the energy absorbed from your body if you melt 0.60 kg of -7 ∘C snow using a stove and drink the resulting 0.60 kg of water at 3 ∘C, which your body has to warm to 37∘C.

Mountain climbers often brew tea by melting snow, which they heat over a stove. Our stove burns butane (C4H10), which has a heat of combustion of -2878 kJ/mol. The temperature of the snow is initially at -20 °C, and we need 80 °C water to brew tea. a. How much heat is needed to turn the snow into a cup (237 mL) of water hot enough to make a cup of tea? b. Calculate the mass of butane needed to...

Thermal question
A 60-kg hiker plans to climb Mt Kosciuszko (2228 m) starting from Thredbo (1365m). Assume that she is 25% efficient at converting chemical energy from food into mechanical work, and that essentially all the work goes into the vertical climb. (a) (3 marks) With reference to the data above, how many servings of Nutrigrain should she eat to provide enough energy for the climb? (b) (6 marks) Climbing a mountain warms you up, and makes you sweat one...

7 Chapter Task The Half-Life of Caffeine Caffeine is a stimulant found in many products, such as coffee, tea, pop, and chocolate. When you drink a cup of tea or eat a chocolate bar, you ingest caffeine. Your body breaks down caffeine slowly. As with other drugs, caffeine has a half-life in the body. The half-life of caffeine in a typical nonsmoking adult is 5.5 h. Caffeine Content (mg) 250 mL...
