What will be the final temperature if a 4.00 g silver ring at 41.0◦c if it gives off 18.0 j of heat to the surroundings? the specific heat capacity of silver is 0.235 j/(g c) express your answer in ◦c.

Final temperature,

Explanation:

Given that,

Mass of silver ring, m = 4 g

Initial temperature,

Heat released, Q = -18 J (as heat is released)

Specific heat capacity of silver,

To find,

Final temperature

Solution,

The expression for the specific heat is given by :

So, the final temperature of silver is 21.85 degrees Celsius.

its a 5.5 n

glad that

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
