The heat lost by the glass is 126 J
Explanation:
The amount of heat lost by a substance is proportional to the change in temperature of the substance according to the following equation:
[tex]Q=mC_s \Delta T[/tex]
where
Q is the amount of heat lost
m is the mass of the substance
[tex]C_s[/tex] is the specific heat capacity of the substance
[tex]\Delta T[/tex] is the change in temperature
In this problem, we have:
m = 10.0 g is the mass of the glass
[tex]\Delta T = -15^{\circ}C[/tex] is the change in temperature of the glass
[tex]C_s = 0.840 J/g{\circ}C[/tex] is the specific heat capacity of glass
Substituting and solving for Q, we find
[tex]Q=(10)(0.840)(-15)=-126 J[/tex]
So, the heat lost by the glass is 126 J.
