plz If you have a 92.3 gram sample of silver that releases 1000.0 J energy, what is the temperature change of the water in a calorimeter if the specific heat of silver is 0.240 J/(goC)?

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

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
