Stoichiometry - Engineering

Q1:

Pick out the wrong unit conversion.

A 1 Joule = 4.186 calorie.

B 1 kcal = 3.968 BTU = 0.00116 kWh = 0.00156 hp.

C 1 ton of TNT (tri-nitro-toluene) = 4.2 GJ (1G = 109).

D 1 ft.lbf= 0.3238 calorie = 0.1383 kg.m = 1.356 J = 1.356 N.m.

ANS:A - 1 Joule = 4.186 calorie.

The wrong unit conversion is:

  1. 1 ton of TNT (tri-nitro-toluene)=4.2 GJ (1G = 109)1ton of TNT (tri-nitro-toluene)=4.2GJ (1G = 109).
This conversion is incorrect because 1 ton of TNT is equivalent to approximately 4.184 GJ, not 4.2 GJ. Therefore, the correct answer is option 3.
