Question

what do you mean by the statement specific heat capacity of lead is 130j/kgk

Answer 1

The specific heat capacity of a substance is the quantity of heat energy required to raise the temperature of 1 kg of the substance by 1°C. The symbol used for specific heat capacity is c and the units are J/(kg °C) or J/(kg K). (Note that these units may also be written as J kg–1 °C–1 or J kg–1 K–1).
Some lead having a specific heat capacity of 130 J/(kg °C) is heated from 27°C to its melting point at 327°C. If the quantity of heat required is 780 kJ, determine the mass of the lead.

Answer 2

Answer:

Thus, a specific heat capacity of lead is 130 JKg-1K-1, means that 1 kg of lead requires 130J of heat energy to raise its temperature through 1K.
