A20.0 g sample of copper at 25.0 °c absorbs 475 j. what is the final temperature of the copper? (specific heat capacity of copper is 0.385 j/g °c.)

Given data:

Mass of copper (m)  = 20.0 g

Initial temperature of Copper (T1)=  25 C

Final temperature = T2

Heat absorbed by copper (Q) = 475 J

Specific heat of Copper (c) = 0.385 J/g C

Formula:

Q = mcΔT

   = mc(T2-T1)

475 = 20*0.385*(T2-25)

62.08 = T2-25

T2 = 87.08 = 87.1 C

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
