Does temperature increase or decrease when going from gas to solid?
The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
Will NaOH increase decrease or no change in pH when added to water?
increase
Does the solubility of potassium nitrate in water increase or decrease as the temperature rises?
Increase
You add baking soda to water will the temp of the water increase or decrease?
it will increase just a little bit
Will H2C2O4 increase decrease or no change in the pH when added to water?
the pH will decrease slightly as oxalic acid is a weak acid.
Will water vapour decrease in amount after being exhaled by a human and before it was inhaled by a human?
exhaled water vapor will be greater than inhaled water vapor
Why does exhaled air saturated with water vapour?
water vapour is produce during respiration
When a cloud forms does the temperature of the atmosphere increase or decrease?
Increase:- When water vapour condenses out of the air to form water droplets, the energy (the latent heat) in the water vapour is released into the surrounding air and the air is warmed.
How go you know that the air exhaled by us contains water vapour?
because it condenses into water when your hot breath is exhaled onto a cold object.
Explain the amount of various gases in an inhaled and an exhaled air?
Inhaled airNitrogen: 78%Oxygen: 21%Carbon Dioxide: 0.04%Water Vapour: 0.96%Exhaled AirNitrogen: 78%Oxygen: 17%Carbon Dioxide: 4%Water Vapour: 3%
Does temperature increase or decrease when going from liquid to gas?
The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
Why exhaled air has more water vapour?
No. The exhaled air contents more water vapour. The exhaled air is almost saturated with water vapour.
When you exhale you breathe this plus co2?
Trace amounts of water vapour are also exhaled, alongside the carbon dioxide.
Will the rate of evaporation of an aqueous solution decrease with increase in humidty?
Humidity is basically the amount of water vapour in the air. And evaporation is the vaporization of water into water vapour. So when the humidity is high there are already plenty of water molecules in the air so the water which gets vapourized into water vapour takes time to fill the gaps in the atmosphere and thus rate of evaporation is slow.
What is occurring when you can see your breath on cold days?
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
Does temperature increase or decrease when going from gas to solid?
The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
How does gravity affect condensation?
Well, if you increase the pressure of the atmosphere, isothermally, around water high enough, then you will overcome the 'vapour pressure' of the water, or the pressure of the water's surface back on the atmosphere to put is very, very simply. SOOOO, if you increase gravity, then you increase atmospheric pressure, which will condense any water vapour in the air. You can decrease gravity to see that the vapour pressure of the newly condensed liquid water will overcome the atmospheric pressure and vaporize. Keep in mind this works in standard conditions, not at extreme temperatures and pressures.
