“c” the specific heat capacity of a substance is given by temperature difference is given by ΔT and the heat energy is given by Q then what is the mass of the substance?(a) Q/cΔT(b) cΔT /Q(c) QcΔT(d) QΔTThis question was addressed to me in class test.Origin of the question is Thermodynamics topic in section Thermodynamics of Chemistry – Class 11 |

Answer» RIGHT option is (a) Q/cΔT For explanation I would say: Heat ENERGY of a substance is denoted by Q and is given by the expression mcΔT, where m is a mass of the substance, c is a specific heat capacity and ΔT is TEMPERATURE difference, so the mass of the substance is Q/cΔT. |
