fenomeno por el que algunos materiales que contiene hierro y que, al contactarse con un iman ,adquieren la propiedad de traer a otros metales que tambien contienen hierro

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

The heliocentric and the geocentric models of the solar system included these central principles

Which model displays the change in a gas when the temperature of the gaseous system decreases?
