Answer :
Q = mc∆T
m = mass
c = specific heat capacity
∆T = change in temperature
Q = mass x specific heat x change in temperature
Q1 = 1 * 390 * 10 = 3900
Q2 = 1 * 4186 * 10 = 41,860
Q3 = 1 * 840 * 10 = 8,400
Add them all up to get the total energy needed to increase the temperature of the whole set by 10°C.
3900 + 41860 = 45,760
45,760 + 8,400 = 54,160
Therefore, 54,160J is needed to increase the temperature by 10°C.
Answer:
51000 J
Explanation:
Change in energy = Mass × Specific Heat Capacity × Change in Temperature
→ Change in energy is measured in joules (J)
→ Mass is measured in kilograms (kg)
→ Specific heat capacity is measured in joules per kilogram per degree Celsius (J/Kg°C)
→ Temperature change is measured in degrees Celsius (°C)
Change in energy for copper = 1 × 390 × 10 = 3900 J/Kg°C
Change in thermal energy for water = 1 × 4180 × 10 = 41,800 J/Kg°C
Change in thermal energy for glass = 1 × 840 × 10 = 8,400 J/Kg°C
Add them all up to get the total energy
3900 + 41800 + 8400 = 51000 J
