<h3><u>Answer;</u></h3>
Strengths of intermolecular forces of the liquid molecules exceed the kinetic energy of the molecules.
<h3><u>Explanation;</u></h3>
- Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered to its freezing point.
- Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat is released.
- Freezing occurs when the molecules of a liquid slow down enough that their attractions cause them to arrange themselves into fixed positions as a solid.
The correct letter of the answer that states why strong acids are good conductors of electricity is letter B, it is because strong acids have the ability to completely ionize in water, giving the ability of being a good conductor towards electricity. Other choices are incorrect because it applies that it is a poor conductor or it only partially ionize water.
Answer:
When the pressure of the vessel is decreased by a factor of three, the volume will increase by a factor 3. This means the new volume is 96.00 L
Explanation:
Step 1: Data given
Volume of the gas = 32.00 L
Pressure of the gas = 1.59 atm
Temperature and moles of gas stay constant
the pressure of the vessel is decreased by a factor of three
Step 2: Calculate the new volume
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 1.59 atm
⇒with V1 = the initial volume = 32.00 L
⇒with P2 = the decreased pressure = 1.59 / 3 = 0.53 atm
⇒with V2 = the new volume = TO BE DETERMINED
1.59 atm * 32.00 L = 0.53 atm * V2
V2 = (1.59 * 32.00 L) / 0.53 atm
V2 = 96.00 L
When the pressure of the vessel is decreased by a factor of three, the volume will increase by a factor 3. This means the new volume is 96.00 L
Answer:
c. carbon dioxide deficiency
Explanation:
Structural fire is occurring in residential or industrial buildings, which means indoors.
This is quite dangerous because all the smoke and toxic gases building up in these closed buildings. Temperature can rise up to extremely high values, especially if fire catches in industrial buildings where fuel or petrol is being used. Fire can also destroy carrying walls causing the building to collapse.
Some of the gases produced during fire are carbon monoxide and carbon dioxide which, found in high enough concentration, cause oxygen deficiency.
