Consider … WebThe heat capacity at constant volume, C v, is the derivative of the internal energy with respect to the temperature, so for our monoatomic gas, C v = 3/2 R. The heat capacity at …

WebThe heat capacity ratio is important for its applications in thermodynamical reversible processes, especially involving ideal gases; the speed of sound depends on this factor. To understand this relation, consider the following thought experiment. A closed pneumatic cylinder contains air. The piston is locked. In physics and chemistry, "monatomic" is a combination of the words "mono" and "atomic", and means "single atom". It is usually applied to gases: a monatomic gas is a gas in which atoms are not bound to each other. Examples at standard conditions of temperature and pressure include all the noble gases … Meer weergeven The only chemical elements that are stable single atoms (so they are not molecules) at standard temperature and pressure (STP) are the noble gases.
