The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called its
a. specific heat
b. heat transfer
c. change of state
d. melting point

Specific heat

Explanation:

Specific heat capacity is the amount of energy required to raise the temperature of 1 kilogram of a substance by 1 Kelvin. According to the formula for heat capacity,(H)

H = mc∆t where m is the mass of the object, c is the specific heat capacity and ∆t is the change in temperature.

Specific heat capacity (c) from the formula will be c = H/m∆t

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
