Thermal Energy Sample Problems
- How much heat is absorbed by 60 g of copper (c=385 J/kg K) when it is heated
from 20°C to 80°
C?
- A 38 kg block of lead (c=130 J/kg K) is heated from -26
°C to 180°
C. How much heat is absorbed?
- A 0.5 kg sample of water is in a calorimeter at 15
°C. 0.04 kg of zinc (c=388 J/kg K) is added. What is the
final temperature? Initial temperature of the zinc is 300
°C.
- 100 g of brass (c=376 J/kg K) at 90°
C is added to 200 g of water at 20°
C. What is the final temperature?
- 100 g of aluminum at 100°
C is added to 100 g of water at 10°
C. What is the specific heat of aluminum if the final temperature of the mixture is 25°
C?
- 100 g of ice at 0°
C is heated until it becomes water at 20°
C. How much heat is added?
- 100 g of water at 0°
C is frozen, becoming ice (c=2060 J/kg K) at -20°
C. How much heat was removed?
