Si unit heat
WebbCorrect option is C) A form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation. It's SI unit is Joule (J). Solve any question of Thermodynamics with:- Patterns of problems > The SI unit for heat capacity of an object is joule per kelvin (J/K or J⋅K ). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same unit as J/°C. The heat capacity of an object is an amount of energy divided by a temperature change, which has the dimension L ⋅M⋅T ⋅Θ . Therefore, the SI unit J/K is equivalent to kilogram meter squared per
