What amount of heat is removed to lower the temperature of 80 grams of water from 75º C to 45º C? The specific heat of liquid wa
Sindrei [870]

Answer:The correct answer option A.

Explanation:

Q= m\times c\times \Delta T

Q= heat removed from the water

m= mass of the water = 80 grams

c = heat capacity of water= 4.18 J/g°C      

\Delta T={\text{Change in temperature}}=45^oC-75^oC=-30^oC  

Q=80g\times 4.18J/g^oC\times(-30^oC)

Q = -10,032 joules \approx -10,000 Joules

Negative sign indicates that heat was removed from the water.

Heat removed from the water of 80 gram of water is 10,032 Joules.Hence, the correct answer option A.
