A 36.2 g object has a heat capacity of 12.5 J/ oC. How much energy (in J) is required to raise the temperature by 5.73 oC?

iren2701 [21]

Answer:

$\Delta H=2592.825\ J$

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

$\Delta H=m\times C\times \Delta T$

Where,

$\Delta H$ is the enthalpy change

m is the mass

C is the specific heat capacity

$\Delta T$ is the temperature change

Thus, given that:-

Mass of object = 36.2 g

Specific heat = 12.5 J/g°C

$\Delta T=5.73\ ^0C$

So,

$\Delta H=36.2\times 12.5\times 5.73\ J=2592.825\ J$

$\Delta H=2592.825\ J$
