Question

The same amount of energy in the form of heat is added to a 2.00 g strip of each of the following metals. Each piece is initially at 25°C. Metal Specific Heat Capacity (J/gK) 0.897 Ca 0.650 Cu 0.385 Mg 1.020 Which piece of metal will have the highest final temperature? Select one a. Al • b. Ca c. Cu d. Mg e. Cannot be determined

Answer 1

1. The specific cheat capacity is given as = stehen m . c . – Te- m.c » A Tz = a X m . c Here, q= cheat absorbed 1,= initial temperature = 25°C( given) c= specific cheat capacity. m= mass of metal - 29 Thus, final temperature Tz depends an only ce specific cheat capacity). . Tz = 4 + . . [kal al constants] This greater the value of specific cheat cafauty, smaller would be the the form (K)

8 and thence smaller would be the final temperature specific cheat capacity of he = 0.385 which is smallest among all melabs. This so, term ķ would be highest for he. So, Iz = {+tz would be highest for Correct option: © le
