Whenever a sports person engages in a physical activity, there is a lot of sweat. The sweat causes loss of water and electrolytes in the body. So, both need to be restored back to the required amount in the body.
ELECTROLYTES AND WATER.
Answer:
1528.3L
Explanation:
To solve this problem we should know this formula:
V₁ / T₁ = V₂ / T₂
We must convert the values of T° to Absolute T° (T° in K)
21°C + 273 = 294K
70°C + 273 = 343K
Now we can replace the data
1310L / 294K = V₂ / 343K
V₂ = (1310L / 294K) . 343K → 1528.3L
If the pressure keeps on constant, volume is modified directly proportional to absolute temperature. As T° has increased, the volume increased too
Answer:
Similar
Explanation:
Elements that are located in the same vertical colomn or group of the periodic table have similar chemical properties. This is because they have the same amount of valence electrons in the outermost shell.
<u>Answer:</u> The temperature when the volume and pressure has changed is -27.26°C
<u>Explanation:</u>
To calculate the temperature when pressure and volume has changed, we use the equation given by combined gas law. The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
![P_1=725mmHg\\V_1=12L\\T_1=30.00^oC=[30+273]K=303K\\P_2=252mmHg\\V_2=28L\\T_2=?K](https://tex.z-dn.net/?f=P_1%3D725mmHg%5C%5CV_1%3D12L%5C%5CT_1%3D30.00%5EoC%3D%5B30%2B273%5DK%3D303K%5C%5CP_2%3D252mmHg%5C%5CV_2%3D28L%5C%5CT_2%3D%3FK)
Putting values in above equation, we get:
Converting this into degree Celsius, we get:
Hence, the temperature when the volume and pressure has changed is -27.26°C
We know, change in temperature is given by :
Putting all given values, we get :
Hence, this is the required solution.
