Part A What will be the equilibrium temperature when a 227 g block of copper at 283 °C is placed in a 155 g aluminum calorimeter cup containing 844 g of water at 14.6°C? ​

T = 20.84°C

Explanation:

From the law of conservation of energy:

Heat Lost by Copper Block = Heat Gained by Aluminum Calorimeter + Heat Gained by Water

where,

= mass of copper = 227 g

= mass of water = 844 g

= mass of aluminum = 155 g

= specific heat capacity of calorimeter = 385 J/kg.°C

= specific heat capacity of water = 4200 J/kg.°C

= specific heat capacity of aluminum = 890 J/kg.°C

= change in temperature of copper = 283°C - T

= change in temperature of water = T - 14.6°C

= change in temperature of aluminum = T - 14.6°C

T = equilibrium temperature = ?

Therefore,

T = 20.84°C

the answer would be a
