\nThe mass of the material can be calculated using the formula relating heat absorbed, specific heat capacity, mass, and temperature change.
\n<\/section>\n
\nThe formula used is Q = mc\u0394T, where Q is the heat energy absorbed (20 kJ = 20,000 J), m is the mass, c is the specific heat capacity (400 J\/(kg \u00b0C)), and \u0394T is the change in temperature (25 \u00b0C – 15 \u00b0C = 10 \u00b0C). Rearranging the formula to find mass: m = Q \/ (c\u0394T). Plugging in the values: m = 20000 J \/ (400 J\/(kg \u00b0C) * 10 \u00b0C) = 20000 \/ 4000 kg = 5 kg.
\n<\/section>\n
\nSpecific heat capacity is a material property that quantifies the amount of heat required to raise the temperature of one unit mass of the substance by one degree Celsius (or Kelvin). The unit J\/(kg \u00b0C) or J\/(kg K) is commonly used. This calculation assumes no phase change occurs within the given temperature range.
