Answer: 4.56 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 substance = 2.5 g
c = specific heat capacity = [tex]0.372J/g^0C[/tex]
Initial temperature = [tex]T_i[/tex] = 25.0°C
Final temperature = [tex]T_f[/tex] = 29.9°C
Change in temperature ,[tex]\Delta T=T_f-T_i=(29.9-25.0)^0C=4.90^0C[/tex]
Putting in the values, we get:
[tex]Q=2.5\times 0.372\times 4.90^0C[/tex]
[tex]Q=4.56J[/tex]
The heat absorbed by gallium must be 4.56 Joules
