First and second law of thermodynamics
Sometimes the laws of thermodynamics are summarized by saying:
1) You can't get something for nothing.
2) You can't even break even.
Explain how these two statements describe the 1st and 2nd law of thermodynamics.

Is it possible for both the pressure and volume of a monatomic ideal gas to change without causing the internal energy of the gas to change?
The electric field in an electromagnetic wave is given by the following (using the standard units) E=20cos(10^7x-wt) where x is the position along the x-axis.
Find the magnetic field at the center of a set of Helmholtz coils each with radius R=0.1m and each carrying a total current I=1.1A (so if there are N turns, each turn carries current I/N).
The thermal expansion coefficient of copper is about 1.7 x 10-5 / oC. A copper cable has a length of 20 m early in the morning, when the temperature is 15 oC. What is the change in it's length (Lnew-Lold) at noon, when the temperature is 25 oC?
A wire carrying a 2-A current is placed at an angle of 60° with the respect to a magnetic field of strength 0.2 T. If the length of the wire is 0.6 m what is the magnitude of the magnetic force acting on the wire?
An unstable particle with a mass equal to 3.34 multiplied by 10-27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.981c and -0.864c, respectively. Find the masses of the fragments.
A radius of 1.35 cm. a 255-g mass hangs from the other end of a string and is released. Write newtons second law for each of the three objects.
In a diesel engine, the piston compresses air at 309 K to a volume that is 0.0621 of the original volume and a pressure that is 48.3 times the original pressure. What is the temperature of the air after the compression?
