What amount of heat is required to raise the temperature of 25 grams of copper to cause a 15º c change? the specific heat of copper is 0.39 j/gº c.
115 j

150 j

250 j

300 j

Explanation:

Heat required to raise the temperature of the object is given as

here we know that

m = mass of the object

m = 25 grams

s = specific heat capacity of the object

= temperature change

now we know that

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
