What happens to boiling water if the pressure increases or decreases?
water boils when the vapour pressure becomes equal to the external pressure. So if we increase the pressure, the rate of boiling will increase. Think of the vapor pressure as the pressure that is needed to force a bubble to the surface.it lowers
What is the relationship between dew point temperature and air pressure?
Dew point is the temperature at which the air reaches saturation. Warmer air can retain more moisture than cooler air. So, ignoring other factors such as pressure, when the temperature drops to the dew point temperature, the air becomes saturated and therefore, if there is actually moisture in the air (is there a cloud?), it will start to rain or snow.
What temperature would KCL solid be most soluble?
Short answer: You don't say what you are dissolving KCl (potassium chloride) in but we'll assume it is water. Salts like KCl dissolve in water better at higher temperatures. Boiling water (100C or 212 F) is the hottest you can get water without confining it and increasing the pressure. So 212F or 100C is the temperature that KCl is most soluble in water. Longer answer: As you add KCl to water the boiling point of the solution becomes lower. So the real maximum solubility temperature (assuming no pressurization) is less than 212 F (100 C). The easiest way to measure this would be to mix highly purified KCl with highly purified water and boil it to see what the boiling temperature is. You must add enough KCl so that even at boiling temperature you still have some solids left that way you will have a saturated solution which will have as much KCl dissolved as the water can hold.
Does a high pressure weather system cause low RH?
They're linked. High pressure is usually a result of air descending from on high, where its absolute humidity has to be low since its temperature is low. When the air descends it warms without gaining water vapor, so the relative humidity has to drop.
Does altitude increase if air pressure increases?
The pressure drops with altitude. More quickly at first, but more gradually the higher you go. If plotted on a graph, you would get a curve.
Rocks can melt without changing temperature when the pressure exerted on them is .?
Increase
What pressure of 152kpa a gas has a volume of 524cm3 The pressure is decreased without changing the temperature until the volume of the gas is equal to 8.00x102 cm3 what is the new pressure?
What pressure of 152kpa a gas has a volume of 524cm3 The pressure is decreased without changing the temperature until the volume of the gas is equal to 8.00x102 cm3 what is the new pressure?
How can you decrease the pressure of gas in a container without changing the volume of the gas?
You could lower the temperature.
Can proteins absorb or lose heat without changing temperature?
No, proteins can't absorb or lose heat without changing much in temperature. Water has a high heat capacity, so water can absorb or release a great deal of heat energy without changing much in temperature.
What will change the density of an object?
Either a decrease or increase in temperature will change the density of an object.
Is it possible that water could become a solid without the aid of temperature?
Yes it is. If you increase the pressure enough, you could in theory turn water into ice, without changing the temperature. It would, however, have to be close to 0 degrees anyhow. I'm not completely sure of this info, someone could confirm?
How do you increase the volume of a gas without changing its particles?
Lower the pressure.
How can a matter change from solid state to liquid state and reverse the process?
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.
How can granite change to metamorphic without changing into sedimentary?
Through heat and pressure
How can you make a liquid boil without raising its temperature?
By reducing the pressure
How can you decrease pressure of a gas in its container without changing the volume of gas?
lots of ways 1. cool it down 2. give it more space 3. remove some gas
What type of phase change is happening as a solid changes to gas without becoming to a liquid?
Sublimation occurs when solid changes directly to liquid without changing to solid state. Applying pressure and reducing temperature can liquefy gases.
