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?​

Answer:

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

Step-by-step explanation:


Q=m* c* \Delta T


Q=m* c* (T_(2)-T_1)

Where:

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

m = Mass of substance

c = specific heat of a substance


T_1 = Initial temperature


T_2 = Final temperature

We have:

m =
1.0* 10^4 g

c = ? ,
T_1=10^oC,T_2=70^oC

Q =
2.5* 10^3 J


2.5* 10^3 J=1.0* 10^4 g* c* (70^oC-10^oC)


c=(2.5* 10^3 J)/(1.0* 10^4 g* (70^oC-10^oC))


c=0.004167 J/g^oC

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