To convert 105 cal to joules.

Question

A medium-sized banana provides about 105 Calories of energy. (a) Convert 105 Cal to joules. (b) Suppose that amount of energy is transformed into kinetic energy of a 1.00-kg object initially at rest. Calculate the final speed of the object. (c) If that same amount of energy is added to 3.79 kg (about 1 gal) of water at 20.0°C, what is the water’s final temperature?

A pronghorn antelope can run at a remarkable 18 m/sm/s for up to 10 minutes, almost triple the speed that an elite human runner can maintain. For a 32 kgkg pronghorn, this requires an astonishing 3.4 kWkW of metabolic power, which leads to a significant increase in body temperature. If the pronghorn had no way to exhaust heat to the environment, by how much would its body temperature increase during this run? (In fact, it will lose some heat, so the rise won't be this dramatic, but it will be quite noticeable, requiring adaptations that keep the pronghorn's brain cooler than its body in such circumstances.) Assume the efficiency of the pronghorn to be equal to that of human.

percent of a kernel's mass consists of water? Assume that the latent heat of vaporization for stays liquid until its temperature is about 175°C, at which point the kernel ruptures and the a Because of the pressure inside a popcorn kernel, water does not vaporize at 100°C. Instead, it unerheated water turns into steam. How much energy is needed to pop 95.0 g of corn if 14 ater at 175°C is 0.90 times its value at 100°C and that the kernels have an initial temperature of 175°C. Critical Thinking
