The specific heat capacity of lead is 140 J / kg × ° C what does this mean?

The specific heat capacity of a substance C is the coefficient of proportionality between the amount of heat Q that is imparted to the body, its mass m and the change in its temperature Δt: Q = C * m * Δt. According to the definition: the specific heat capacity of a substance is such an amount of heat, when communicated to 1 kg of a given substance, its temperature will change by 1 “C. The specific heat capacity of lead is 140 J / kg, which means that when 140 J of heat energy is transferred to 1 kg of lead, its temperature will increase by 1 “S.
