Sam's bike tire contains 15 units of air particles and has a volume of 160ml. under these conditions the pressure reads 13 psi. the tire develops a leak. now it contains 10 units of air particles and has contracted to a volume of 150ml. what would the tire pressure be now?

Which of the following best describes internal energy? a. the difference between the kinetic and potential energies of the particles in a system b. the sum of the kinetic and potential energies of the particles in a system c. the sum of the kinetic and thermal energies of the particles in a system d. the difference between the kinetic and thermal energies of the particles in a system
