(a)

To determine

The amount of heat transferred from metal to water.

(a)

Expert Solution

Answer to Problem 4SP

The amount of heat transferred from metal to water is 2340 cal.

Explanation of Solution

Given info: A 135 g quantity of a certain metal, initially at 130°C , is dropped into an insulated beaker containing 90 g of water at 20°C . The final temperature of the metal and water in the beaker is 46°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 90 g for m, 1 cal/g⋅°C for c, 20°C for T1 and 46°C for T2 in equation (3)

Q=90 g×1 cal/g⋅°C(46°C−20°C) =2340 cal

Conclusion:

The amount of heat transferred from metal to water is 2340 cal.

(b)

To determine

The specific heat capacity of metal.

(b)

Expert Solution

Answer to Problem 4SP

The specific heat capacity of metal is 0.206 cal/g⋅°C.

Explanation of Solution

Write the expression for specific heat capacity of metal

c=Qm(T2−T1)

Substitute 135 g for m, 2340 cal for Q, 130°C for T1, and 46°C for T2 in the above equation

c=2340 cal135 g(130°C−46°C)=0.206 cal/g⋅°C

Conclusion:

The specific heat capacity of metal is 0.206 cal/g⋅°C.

(c)

To determine

The quantity of metal dropped into the insulating beaker.

(c)

Expert Solution

Answer to Problem 4SP

The quantity of metal dropped into the insulating beaker is 360 g.

Explanation of Solution

Write the expression for heat in terms of specific heat capacity

Q=mcΔT (1)

ΔT is the change in temperature

Write the expression for change in temperature

ΔT = T2−T1 (2)

Substitute equation (2) in (1)

Q=mc(T2−T1) (3)

Substitute 90 g for m, 1 cal/g⋅°C for c, 20°C for T1 and 70°C for T2 in equation (3)

Q=90 g×1 cal/g⋅°C(70°C−20°C) =4500 cal

Write the expression of mass in terms of specific heat capacity

m=QcΔT (4)

Substitute 0.206 cal/g⋅°C for c, 4500 cal for Q, 130°C for T1 and 70°C for T2 in equation (4)

m=4500 cal0.206 cal/g⋅°C×(130°C−70°C)=364 g≈360 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 360 g.
