Heat supplied to a system is measured in

Correct option is D

​$$\bullet \textbf{Heat (Q)} \text{ is a form of } \textbf{energy} \text{ and is measured in } \textbf{joules (J)} \text{ in the SI system.}$$​​

​$$\bullet \text{The relationship between heat, mass, specific heat, and temperature change is given by:}$$​​$$Q = mc\Delta T$$

$$\textbf{where:}$$

$$\bullet \quad Q = \text{Heat energy (Joules)}$$

$$\bullet \quad m = \text{Mass of the substance (kg)}$$

$$\bullet \quad c = \text{Specific heat capacity (J/kg$\cdot$K)}$$

$$\bullet \quad \Delta T = \text{Temperature change (K or $^\circ$C)}$$​​​​​​
