To calculate the energy required to raise the temperature of a substance, we can use the formula:
where:-
is the energy required,-
is the mass of the substance,-
is the specific heat capacity of the substance,-
is the change in temperature.Given:-
grams,- Initial temperature
,- Final temperature
.First, calculate the change in temperature (
):
Next, we need the specific heat capacity (
) of solid chromium. The specific heat capacity of solid chromium is approximately
.Now, plug in the values into the formula:
Calculate
:
Therefore, the energy required to raise the temperature of 11.1
to
is approximately
joules.
