Explanation:
The temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure is known as boiling point.
At the boiling point the liquid and vapor state of a substance remains in equilibrium till the time all molecules of liquid do not turn into vapor.
When all the liquid molecules change into vapor state then only there will occur a rise in temperature.
Properties that do not depend on the amount of matter are known as intensive properties.
For example, boiling point, melting point, density etc.
On the other hand, properties which depend on the amount of matter are called extensive properties.
For example, volume, density etc.
Thus, we can conclude that if you heat a liquid and measure the temperature at which it boils, you are measuring an intensive property.
Answer:
the mass of CaO present at equilibrium is, 0.01652g
Explanation:
![K_p = [CO_2]](https://tex.z-dn.net/?f=K_p%20%3D%20%5BCO_2%5D)
= 3.8×10⁻²
Now we have to calculate the moles of CO₂
Using ideal gas equation,
PV =nRT
P = pressure of gas = 3.8×10⁻²
T = temperature of gas = 1000 K
V = volume of gas = 0.638 L
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mole.k
Now we have to calculate the mass of CaO
mass = 2.95 * 10 ⁻⁴ × 56
= 0.01652g
Therefore,
the mass of CaO present at equilibrium is, 0.01652g
Answer:
it should be velocity and mass
Answer:
the law says the temperature difference between two objects falls exponentially.
doesn't change in time and no heating or cooling would happen.
