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

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

dang that balls went far
