A 100.0g sample of lead is heated to 100.0 oC (Celsius) and is placed in a coffee cup calorimeter containing 150. g of water at
AURORKA [14]

Answer : The specific heat capacity of lead is, 0.119J/g^oC

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

q_1=-q_2

m_1\times c_1\times (T_f-T_1)=-m_2\times c_2\times (T_f-T_2)

where,

c_1 = specific heat of lead = ?

c_2 = specific heat of water = 4.184J/g^oC

m_1 = mass of lead = 100.0 g

m_2 = mass of water = 150.0 g

T_f = final temperature = 26.4^oC

T_1 = initial temperature of lead = 100.0^oC

T_2 = initial temperature of water = 25^oC

Now put all the given values in the above formula, we get

100.0g\times c_1\times (26.4-100.0)^oC=-150.0g\times 4.184J/g^oC\times (26.4-25)^oC

c_1=0.119J/g^oC

Therefore, the specific heat capacity of lead is, 0.119J/g^oC
