Here is a simple heat engine: Start with 20 moles of monatomic gas, occupying 0.50 m3 of volume at 400 K.
a ) Calculate the gas pressure.
i) Add heat at constant pressure until the volume increases to 1.0 m3.
ii) At constant volume, let the gas cool to atmospheric pressure.
iii) Compress the gas at constant pressure to its original volume.
iv) Heat the gas at constant volume to the original pressure.
b) Draw a P-V diagram of this cycle.
c) Calculate the temperature at the end of each process.
d) Find the total work done during the cycle.
The potential difference across a resting neuron in the human body is about 105.0 mV, How much power does the neuron release
A projectile is fired straight upward at 141 m/a. how fast is it moving at the instant it reaches the top of its trajectory? Assume in its place that it was fired upward at 45. What would be its speed at the top of its trajectory.
In a friction experiment, your wooden plank is horizontal. When a mass of 100 grams is hanging on the weight hanger of mass 50 grams, a slight push makes the block move at a constant speed along the plank. If the mass of a wooden block is 500 gram..
