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.
Hello!
Use the equation:
Where:
m = mass of the object (kg)
g = acceleration due to gravity (≈9.8 m/s)
h = height above ground (m)
Plug the given values into the equation:
PE = 7500 · 9.8 · 100
PE = 7,350,000 Joules.
