Explicación
## Step 1The problem involves the calculation of the amount of heat required to increase the temperature of a substance. This is a classic application of the formula for heat transfer, which is given by:###
where:-
is the heat energy (in joules),-
is the mass of the substance (in grams),-
is the specific heat capacity of the substance (in joules per gram per degree Celsius), and-
is the change in temperature (in degrees Celsius).## Step 2In this problem, we are given the following values:- The specific heat capacity of gold,
,- The mass of gold,
, and- The change in temperature,
.## Step 3We can now substitute these values into the formula to calculate the amount of heat energy required.
