What is the specific heat at constant volume (Cv) for a monatomic ideal gas? (2019)
Step 1: Understand what a monatomic ideal gas is. It is a gas made up of single atoms, like helium or neon.
Step 2: Know that specific heat at constant volume (Cv) is the amount of heat required to raise the temperature of a gas when the volume does not change.
Step 3: Recall the formula for specific heat for a monatomic ideal gas, which is derived from kinetic theory and thermodynamics.
Step 4: The formula for Cv for a monatomic ideal gas is Cv = (3/2)R, where R is the universal gas constant.
Step 5: Therefore, for a monatomic ideal gas, Cv = 3R/2.
