Students in a physics lab are to determine the specific heat of copper. They heat 0.890kg of copper shot to 110º C and then carefully pour the hot shot into calorimeter cup containing 0.400kg of water at 20ºC. The final temperature of the mixture in the cup is measured to be 35ºC. If the aluminum cup has a mass of 0.067kg, what is the specific heat of copper?

true

explanation:

answer///scientific method;

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
