Answer: The amount of energy required is 101 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
[tex]Q=m\times c\times \Delta T[/tex]
Q = Heat absorbed = ?
m= mass of gold = 30.0 g
c = specific heat capacity of gold = [tex]0.13J/g^0C[/tex]
Initial temperature of the water = [tex]T_i[/tex] = 15°C
Final temperature of the water = [tex]T_f[/tex] = 41°C
Change in temperature ,[tex]\Delta T=T_f-T_i=(41-15)^0C=26^0C[/tex]
Putting in the values, we get:
[tex]Q=30.0g\times 0.13J/g^0C\times 26^0C[/tex]
[tex]Q=101J[/tex]
The amount of energy required is 101 Joules
