It is necessary to determine the specific heat of an unknown object.The mass of the object is $\text { 201.0 g. }$ It is determined experimentally that it takes $15.0 \mathrm {~J}$ to raise the temperature $10.0 ^ { \circ } \mathrm { C }$ What is the specific heat of the object?

The specific heat is given by the equation:$$c = \frac{Q}{m\Delta T}$$where:* $c$ is the specific heat (in J/kg∙K)* $Q$ is the heat added (in J)* $m$ is the mass (in kg)* $\Delta T$ is the change in temperature (in K)In this problem, we have:* $Q = 15.0 \mathrm{~J}$* $m = 201.0 \mathrm{~g} = 0.2010 \mathrm{~kg}$* $\Delta T = 10.0 ^\circ \mathrm{C} = 10.0 \mathrm{~K}$Substituting these values into the equation, we get:$$c = \frac{15.0 \mathrm{~J}}{0.2010 \mathrm{~kg} \times 10.0 \mathrm{~K}} = 7.46 \mathrm{~J/kg∙K}$$Therefore, the specific heat of the object is 7.46 J/kg∙K.
