How much heat is transferred when a 25.25 g piece of copper is heated from 10 degrees C to 18 degrees C? Cp = 0.38452 J/g x oC

Sagot :

Heat transferred : Q = 77.673 J

Further explanation

Given

mass of Copper = 25.25 g

Temperature from 10 °C to 18 °C

Cp = The specific heat of Copper = 0.38452 J/g °C

Required

Heat transferred

Solution

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Input the value :

Q = 25.25 g x 0.38452 J/g °C x (18 - 10)

Q = 77.673 J
