A68 g sample of copper is at 20â¦c. if 1918 j of energy are added to the copper, what is its final temperature? assume the specific heat of copper is 387 j/kg â·â¦ c. answer in units of â¦c.

Final temperature of the sample is 92.88 degrees Celsius.

Explanation:

It is given that,

Mass of the sample of copper, m = 68 g = 0.068 kg

Initial temperature,

Energy added to the copper, Q = 1918 J

Specific heat of the copper,

We need to find the final temperature of the copper sample. The heat added is given by :

, T₂ is the final temperature

So, the final temperature of the copper sample is 92.88 degrees Celsius. Hence, this is the required solution.

wavelength variability is the right one

it is called kinetic energy
