Explain how the first law of thermodynamics relates to metabolism in humans. click here to enter text. 1. 2. initially there is a balloon that holds half of a mole of an ideal gas with a volume of 1.5 l at 273 k. then 1500 j of heat is added to the balloon, and the balloon expands to 4.0 l. using the ideal gas law (pv =nrt) where r 8.3141 k-1mol-', the equation for work, and the first law of thermodynamics, what is the change in internal ergy of the balloon at the end of the process? click here to enter text. 3. a thermodynamic process that maintains a constant volume is called an isochoric process. during these types of processes, the gas does no work because it is not increasing the volume of the container. if you sealed off the top of a water bottle and shook 100 ml of water for two minutes, you would find that the water is warmer when you take a drink. if you shook the water long enough to raise the water's temperature 5°c, what is the change in internal energy of the system?

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.
