Identify which of the following pairs of physical quantities can be expressed using the same unit.
Options
- AHeat and temperature
- BTemperature and mole
- CSpecific heat and heat
- DHeat and work
Correct answer
D. Heat and work
Step-by-step solution
Heat is a form of energy, and its SI unit is Joule (J).
Work is defined as the product of force and displacement, which also represents energy transfer, and its SI unit is Joule (J).
Temperature is measured in Kelvin (K) or Celsius (^{{}^{{}^{\circ}}}C).
Mole is the unit for the amount of substance.
Specific heat capacity has the unit J/(kg K).
Therefore, only heat and work can be expressed using the same unit.
