What is the meaning of superheat in aircontioning?
Superheat in air conditioning refers to the additional heat added to a vapor after all of the liquid has vaporized. It is used to ensure the refrigerant leaving the evaporator is in a completely gaseous state, which helps prevent liquid refrigerant from entering the compressor. Superheat is important for maintaining the efficiency and proper operation of the air conditioning system.
How does the process of burning candles work?
When a candle is lit, the heat from the flame melts the wax near the wick. The liquid wax is drawn up the wick by capillary action and is vaporized by the heat of the flame. The vaporized wax combines with oxygen in the air and burns, producing heat, light, and carbon dioxide.
Which two physical quantities must be measured in order to determine the density of a liquid?
To determine the density of a liquid, two physical quantities that must be measured are the mass of the liquid and the volume of the liquid. Density is calculated by dividing the mass of the liquid by its volume.
A 30ml sample of an unknown liquid has a mass off 100g what is the density?
Density is calculated by dividing the mass of a substance by its volume. In this case, the density of the unknown liquid is 100 g / 30 ml = 3.33 g/ml.
How is density used to determine if a material will float or sink in a liquid?
Density is used to determine if a material will float or sink in a liquid by comparing the density of the material to the density of the liquid. If the material has a greater density than the liquid, it will sink. If the material has a lower density than the liquid, it will float. Objects float when they displace an amount of liquid equal to their own weight.
If a liquid sample of naphthalene is heated and remains at 218 and degC until it is completely vaporized you know that 218 and degC is the of naphthalene.?
Boiling point.
If a liquid sample of naphthalene is heated and remains at 218 until it is completely vaporized you know that 218 is the of naphtanlene?
If a liquid sample of naphthalene is heated and remains at 218°C until it is completely vaporized, you know that 218°C is the boiling point of naphthalene. This temperature indicates the point at which the liquid naphthalene transitions to its gaseous state under atmospheric pressure. The boiling point is a characteristic property of a substance and helps identify it.
What is the process to calculate the gram molecular weight of the unknown liquid?
To calculate the gram molecular weight of an unknown liquid, you need to determine the molecular formula of the liquid and then add up the atomic weights of all the atoms in the formula. This will give you the gram molecular weight of the unknown liquid.
When gas changed into liquid?
When it vaporized with heat
Suppose you were given an unknown liquid and asked to determine if it was an element a compound or a mixture What would you do How would this help you find out what it was?
If I was given an unknown liquid and asked to determine if it was an element, a compound, or a mixture I would heat the unknown liquid up to see if any compounds separated from the unknown liquid. After that I would get a microscope and look to see if it is a pure element. Then I would get a Platelet separation machine and put the liquid in the machine to see if the liquid separated. Thats how I would determine if the an unknown liquid is an element, a compound, or a mixture.
What does vaparized mean?
When a liquid turns into a gas. The steam that comes out of hot water is vaporized water.
What is mean saturated liquid and vapor?
A liquid or vapor is saturated when it is at the temperature and pressure where it would be in equilibrium with the other phase; saturated liquid at the boiling point or saturated vapor at the dew point. If the pressure is raised, the vapor will condense until the pressure is restored to the original pressure or all the vapor is condensed. If the pressure is dropped, a saturated liquid will boil until the pressure rises back to the original pressure or all the liquid has vaporized. If the temperature is increased, a saturated liquid will boil off completely unless the vaporized liquid raises the pressure enough to establish a new equilibrium. If the temperature is dropped, a saturated vapor will condense until the pressure has dropped enough to establish a new equilibrium.
What is the density of the unknown liquid rho unknown?
1.51
When a liquid changes to a gas we say it?
When a liquid changes to a gas, we say it has vaporized or evaporated. This process occurs when the liquid's molecules gain enough energy to overcome the forces holding them together in the liquid state.
What is saturated phase?
The saturated phase is a phase in which a substance exists at a temperature and pressure where it is in equilibrium between its liquid and vapor states. In this phase, the substance's properties such as temperature, pressure, and composition remain constant until all the substance has completely vaporized or condensed.
Why are the sates of matter unknown?
They aren't unknown- there is gas, liquid and solid
Explain how you would find the density of an unknown liquid if you have all the laboratory equipment that you need?
To find the density of an unknown liquid, you would weigh a known volume of the liquid using a balance to determine its mass. Then, you would divide the mass by the volume to calculate the density. Make sure to use the proper units for mass (grams) and volume (milliliters or cubic centimeters) in your calculation.
