The final temperature : 317 °C

<h3>Further explanation</h3>

Given

V₁=2.5 L

V₂ = 5 L

T₁ = 22 + 273 = 295 K

Required

The temperature, T₂

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Input the value :

T₂ = (T₁ x V₂) : V₁

T₂ = (295 x 5) : 2.5

T₂ = 590 K = 317 °C

An unknown piece of metal weighing 95.0 g is heated to 98.0°C. It is dropped into 250.0 g of water at 23.0°C. When equilibrium i

Answer:

C_{metal}=126.6\frac{J}{g\°C}

Explanation:

Hello!

In this case, when two substances at different temperature are put in contact and an equilibrium temperature is attained, we can evidence that the heat lost by the hot substance (metal) is gained by the cold substance (water) and we can write:

Q_{metal}=-Q_{water}

Which can be also written as:

m_{metal}C_{metal}(T_{EQ}-T_{metal})=-m_{water}C_{water}(T_{EQ}-T_{water})

Thus, since we need the specific heat of the metal, we solve for it as shown below:

C_{metal}=\frac{m_{water}C_{water}(T_{EQ}-T_{water})}{-m_{metal}(T_{EQ}-T_{metal})} \\\\C_{metal}=\frac{250.0g*4.184\frac{J}{g\°C}(29.0\°C-98.0\°C)}{95.0g(29.0\°C-23.0\°C)} \\\\C_{metal}=126.6\frac{J}{g\°C}

Best regards.

I NEED HELP PLEASE, THANKS!
Xelga [282]

Answer:

See explanation

Explanation:

In the scientific method, you always begin with asking a question. Then, you do research, make a hypothesis, and test that hypothesis based on the initial question. If experimental data does not support your hypothesis, then you can restart by asking a new question, based on what you already know. Hope this helps!
