What is the specific heat of a substance that absorbs 2.5×10^3 joules of heat when a sample of 1.0 ×10^4g of the substance increases in temperature from 10°c to 70°c?

0.004167 J/g°C is the specific heat of a substance.

Explanation:

Where:

Q =  heat absorbed(positive) or released (negative)

m = Mass of substance

c =  specific heat of a substance

= Initial temperature

= Final temperature

We have:

m =

c = ? ,

Q =

0.004167 J/g°C is the specific heat of a substance.

im not exactly sure but i think its b!
