Specific heat capacity of nickel

Asked by maham237 @ 12/01/2021 in Physics viewed by 291 People

A 275-g sample of nickel at 100.0°C is placed in 100.0 mL of water at 22.0°C. What is the final temperature of the water? Assume that no heat is lost to or gained from the surroundings. Specific heat capacity of nickel = 0.444 J/(g·K)

Answered by maham237 @ 12/01/2021

Answer:

39.6138 °C

Explanation:

Heat gain by water = Heat lost by nickel

Thus,

$m_{water}\times C_{water}\times (T_f-T_i)=-m_{nickel}\times C_{nickel}\times (T_f-T_i)$

Where, negative sign signifies heat loss

Or,

$m_{water}\times C_{water}\times (T_f-T_i)=m_{nickel}\times C_{nickel}\times (T_i-T_f)$

For water:

Volume = 100.0 mL

Density of water= 1 g/mL

So, mass of the water:

$Mass\ of\ water=Density \times {Volume\ of\ water}$

$Mass\ of\ water=1 g/mL \times {100.0\ mL}$

Mass of water = 100 g

Initial temperature = 22.0 °C

Specific heat of water = 4.186 J/g°C

For nickel:

Mass = 275 g

Initial temperature = 100 °C

Specific heat of nickel = 0.444 J/gK = 0.444 J/g°C

So,

$100\times 4.186\times (T_f-22.0)=275\times 0.444\times (100-T_f)$

$418.6\times (T_f-22.0)=122.1\times (100-T_f)$

$418.6\times T_f+122.1\times T_f=21419.2$

$T_f=39.6138\ ^{0}C$

Thus,

The final temperature of the combined metals is 39.6138 °C
