1. Specific Heat Capacity.
A. Heat on concrete
The specific heat capacity of concrete is 0.880 J/g °C
Calculate the heat added to 3 g of concrete if the temperature increased by 0.64 °C
Use the equation q=mcat

B. Hot water
The specific heat capacity of water is 4.186J/g °C
Calculate the temperature change when 8000 J of heat is added to 3g of water,
Use the equation q=mcat

Answer:

B.

Solution given:

specific heat capacity of water [c]4.186 J/g °C

temperature[∆T]=?

mass[m]=3g

heat[Q]=8000J

we have

Q=mc∆T

8000=3*4.186*∆T

∆T=8000/12.558

∆T=637.04°C.

the temperature change is 637.04°C.
