Isotherm- a line of constant temperature
Isobar- a line of constant pressure
________ . ________________________100 km apart____________________________ . _______________
A (temp, pressure) equal B(temp, pressure)
All forces in balance, the sum of net forces is equal to zero. However acting in different
temperatures and pressures. Not equivalent. No net motion, because they are in
balance.
NOW:
Point B is warmer than point A.
________ . ______________________equal units apart__________________________ . _______________
