How much thermal energy is lost from a glass casserole dish?

Question:

What is the amount of thermal energy lost from a 0.5 kg glass casserole dish when its temperature changes from 110˚C to 50˚C?

Answer:

The amount of thermal energy lost from the glass casserole dish is -25200 J.

To evaluate the amount of thermal energy lost from the glass casserole dish, we can use the equation for the change in thermal energy: E = mcΔT. First, we need to find the specific heat for glass, which is typically around 840 J/kg·°C. By substituting the values into the equation, we find that the thermal energy lost from the dish is -25200 J.
