Explanation Given data: M w is 5.0 kg . M s is 1.0 kg . T f,s is 500 ° C . c s is 800 J kg ⋅ K . T i,w is 10 ° C . Formula used: Write the expression for heat ( Q ) . Q = M c Δ T (1) Here, M is the mass, c is the specific heat, and Δ T is the change in temperature. Consider the expression for change in temperature ( Δ T ) Δ T = T f − T i (2) Here, T f is the final temperature, and T i is the initial temperature. Explanation: Refer to TABLE 12.4 in the textbook for Specific heats of solids and liquids. The specific heat of water ( c w ) is 4190 J kg ⋅ K . Modify equation (2) for water. Δ T w = T f,w − T i,w Consider n be the minimum number of stones required to boil water. Modify equation (1) for water. Q w = M w c w Δ T w Substitute T f,w − T i,w for Δ T w , Q w = M w c w ( T f,w − T i,w ) Modify equation (2) for stone. Δ T s = T f,s − T i,s Modify equation (1) for stone. Q s = n M s c s Δ T s Substitute T f,s − T i,s for Δ T s , Q s = n M s c s ( T f,s − T i,s ) Consider the initial temperature of stone ( T i,s ) and final temperature of water ( T f,w ) as 100 ° C As the heat lost by stone is the heat gained by water. Therefore, Q s = Q w Substitute M w c w ( T f,w − T i,w ) for Q w and n M s c s ( T f,s − T i,s ) for Q s , n M s c s ( T f,s − T i,s ) = M w c w ( T f,w − T i,w ) Rearrange the equation
