The SI unit of mechanical equivalent of heat is
1 \(\mathrm{J} / \mathrm{cal}\)
2 J-cal
3 cal. erg
4 \(\operatorname{erg} / \mathrm{J}\)
Explanation:
A Mechanical equivalent of heat, if the work is completely changed to the heat energy, then the some amount of heat is generated. Mathematically, \(\mathrm{J}=\frac{\mathrm{W}}{\mathrm{q}}\) Here, \(\quad W=\) Amount of work required to generate heat \(\mathrm{q}=\) Amount of heat \(=\frac{\text { Joule }}{\text { Calorie }}\) So, SI unit of mechanical equivalent of heat is \(\mathrm{J} / \mathrm{cal}\).
