Determine the specific heat of a material if a 15 gram sample absorbs 75 J of heat as it is temperature increases from 15°C to 4

Roman55 [17]

Answer:

$Cp=0.2\frac{J}{g\°C}$

Explanation:

Hello,

In this case, the heat, mass, specific heat and temperature change are related by:

$Q=mCp\Delta T$

Thus, if we want to compute the specific heat we simply solve for it:

$Cp=\frac{Q}{m\Delta T}=\frac{75J}{15g*(40-15)\°C} \\\\Cp=0.2\frac{J}{g\°C}$

Best regards.
