Question

I need this like now !!! plz

Answer 1

Answer:

45.1°C

Explanation:

Given parameters:

Mass of the silver = 92.3g

Quantity of energy released  = 1000J

Specific heat of silver  = 0.24J/g°C

Unknown:

Temperature change of the water  = ?

Solution:

To solve this problem, we use the expression below:

     H  = m c Ф

H is the quantity of heat

m is the mass

c is the specific heat capacity

Ф is the temperature change

  Insert the parameters and solve;

           1000 = 92.3 x 0.24 x Ф

            1000 = 22.15Ф

              Ф   = 45.1°C
