Question

what happens to the temperature of the gas during an isobaric expansion? view available hint(s)for part b temperature increases. temperature remains constant. temperature decreases.

Answer 1

During isobaric expansion with the addition of heat, the temperature of the gas increases because the average kinetic energy of the gas particles increases. If the gas is ideal and the expansion is free without external heat, the temperature would remain constant.

Step-by-step explanation:

During isobaric expansion, when the gas expands at constant pressure as its temperature is increased in small steps through the use of a series of heat reservoirs, the general behavior is that the volume of the gas increases as the temperature increases. In the case of an ideal gas, the internal energy depends only on the temperature; thus, if the expansion is free, the temperature would not change. However, if heat is added, as described by the heat reservoirs, then the temperature of the gas will increase as it expands isobarically.

This change in temperature during isobaric processes reflects the kinetic energy of the gas particles. If heat is transferred to the gas, the average kinetic energy of the gas particles increases, which corresponds to an increase in temperature. Conversely, if an isobaric process occurs without the addition of heat, the temperature of the ideal gas would remain constant.
