Answer:
51520J
Explanation:
The energy added to the piece of glass is also called heat needed to increase its temperature from 10°C to 50°C and it depends on the mass, specific heat capacity and the change in temperature.
Q=m.c.ΔT
Q=(2kg).(644J/(kg°C)).((50°C)-(10°C))
Q=51520J
Ok? I don’t know what you want me to do though
