if 162.4 j of heat are added to a gas contained within a cylinder and the gas expands, doing 87.3 j of work, what is the change
labwork [276]

The changes in internal energy of the system <u>75.1 J.</u>

The internal energy of a thermodynamic system is the total energy contained in it. It is the energy required to create or prepare a system in a given internal state and includes contributions of potential energy and internal kinetic energy.

Calculation:

Internal energy =  162.4 j - work done

                        =  162.4 j - 87.3 j

                         =<u> 75.1 J</u>

<u />

Internal energy, in thermodynamics, is the property or state function that defines the energy of matter in the absence of capillary action or external electric, magnetic, or other fields.

Internal energy is the microscopic energy contained in the matter given by the random and disordered kinetic energy of the molecules. It also includes the potential energy between these molecules and the nuclear energy contained in the atoms of these molecules.

A gold nucleus is 466 fm (1 fm = 10-15 m) from a proton, which initially is at rest. When the proton is released, it speeds away
Artist 52 [7]

Answer:

v=6.8\times10^6m/s

Explanation:

The sum of the kinetic and electric potential energies of the proton when initially released must be equal to their sum at infinity, so we have:

K_i+U_i=K_f+U_f

Which, since K_i=0J because initially the proton is at rest, is:

\frac{kqQ}{d}=\frac{mv^2}{2}+\frac{kqQ}{r_\infty}

where k=9\times10^9Nm^2/C^2 is Coulomb's constant, q=1.6\times10^{-19}C the charge of the proton, Q=(79)(1.6\times10^{-19})C the charge of the gold nucleus, since it has 79 protons, d=466\times10^{-15}m the initial separation between them, m=1.67\times10^{-27}kg the mass of the proton and v its final velocity. r_\infty is very far away, so the final electric potential will be 0J, and we have:

v=\sqrt{\frac{2kqQ}{md}}=\sqrt{\frac{2(9\times10^9)(1.6\times10^{-19})^2(79)}{(1.67\times10^{-27})(466\times10^{-15})}}m/s=6839409m/s
