Match each physical quantity listed on the left with its corresponding classification and physical description on the right.
- Electric potential differenceDerived quantity defined as energy transfer or work done per unit electric charge
- Thermodynamic temperatureFundamental quantity representing thermal state, measured in kelvins ()
- ImpulseDerived quantity defined as the product of force and time interval
- Luminous intensityFundamental quantity measuring perceived light power per unit solid angle
Answer
Electric potential difference matches derived quantity defined as work done per unit electric charge; Thermodynamic temperature matches fundamental quantity representing thermal state, measured in kelvins; Impulse matches derived quantity defined as force times time interval; Luminous intensity matches fundamental quantity measuring perceived light power per unit solid angle.
Thermodynamic temperature and luminous intensity are two of the seven fundamental SI quantities. Electric potential difference and impulse are derived quantities because they are expressed through equations involving base physical quantities.
