To determine

The quantity of heat was dropped from metal to insulating beaker.

Answer to Problem 4SP

The quantity of heat was dropped from metal to insulating beaker is 327 g.

Explanation of Solution

Given info: A 170 g quantity of a certain metal, initially at 125°C , is dropped into an insulated beaker containing 84 g of water at 16°C . The final temperature of the metal and water in the beaker is measured as 39°C.

Write the expression for heat in terms of specific heat capacity

Q=mcΔT (1)

Here,

Q is the heat

m is the mass

c is the specific heat capacity of ice

ΔT is the change in temperature

Write the expression for change in temperature

ΔT = T2−T1 (2)

Here,

ΔT is the change in temperature

T1 is the initial temperature

T2 is the final temperature

Substitute equation (2) in (1)

Q=mc(T2−T1) (3)

Substitute 84 g for m, 1 cal/g⋅°C for c, 16°C for T1 and 53°C for T2 in equation (3)

Q=84 g×1 cal/g⋅°C(53°C−16°C) =3108 cal

Write the expression of mass in terms of specific heat capacity

m=Qc(T2−T1) (4)

Substitute 0.132 cal/g⋅°C for c, 3108 cal for Q, 125°C for T1 and 53°C for T2 in equation (4)

m=3108 cal0.132 cal/g⋅°C×(53°C−125°C)=327 g

The negative sign in the above equation is avoided since mass is always a positive quantity.

Conclusion:

The quantity of heat was dropped from metal to insulating beaker is 327 g.
