# IMAT 2017 Q59 [Ideal Gas Change]

A fixed mass of an ideal gas undergoes a change in which it is supplied with 3500 J of thermal energy. At the same time this gas does 3500 J of work on its surroundings.

Which type of change does the gas undergo during this time?

B. isothermal
C. isochoric
D. isomeric
E. isobaric

The basic processes with ideal gas are known as follows: isothermal, isochoric, isobaric, and adiabatic.

In these systems, one or more variables is held constant.

1. Isobaric; where the pressure of the system is kept constant. \delta P=0

1. Isochoric; where the volume of the system is kept constant. \delta V=0

1. Isothermal; where the temperature of the system is kept constant. \delta U=0 and \delta T=0

Note that when \delta T=0, the relation between Volume and Pressure is inversely proportional.

1. Adiabatic; where no heat is being added or removed from the system (no heat transfer). Q= 0
