Calculate the change in temperature of 1 mole of a gas if it absorbs 500 J of heat at constant volume and has a CV of 20 J/K.
💡 Hint: Use the formula for heat and temperature change.
A gas has Cp = 29 J/(mol K) and CV = 20 J/(mol K). What is the value of R? Use the relationship Cp - CV = R.
💡 Hint: Apply the derived relationship!
