A19.0g sample of brass, which has a specific heat capacity of 0.375·J*g^−1°C−, is dropped into an insulated container containing

djverab [1.8K]

Answer:

The final temperature is 20.3 °C

Explanation:

Considering that:-

Heat gain by water = Heat lost by brass

Thus,

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

Where, negative sign signifies heat loss

Or,

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

For water:

Mass = 300.0 g

Initial temperature = 20.0 °C

Specific heat of water = 4.184 J/g°C

For brass:

Mass = 19.0 g

Initial temperature = 81.7 °C

Specific heat of water = 0.375 J/g°C

So,

$300.0\times 4.184\times (T_f-20.0)=19.0\times 0.375\times (81.7-T_f)$

$1255.2T_f-25104=582.1125-7.125T_f$

$1262.325T_f=25686.1125$

$T_f = 20.3\ ^0C$

<u>Hence, the final temperature is 20.3 °C</u>
