Why is water a liquid at room temperature with a molar volume of 18mL and at 105 degrees C and 1 ATM pressure it is a gas with a molar volume of 30L?

the 30L water vapor sample is a gas
gases exert pressure on their surroundings thus taking on the shape of their containers
the gas is under 1 ATM of pressure so it exerts pressure in return and the volume becomes 30L when the presures are equal
if the temperature were to decrease to room temperature, the water vapor would condense to a liquid and the volume would decrease
liquids have a volume but no definite shape while gases have neither a definite volume or shape

What determines the temperature at which a refrigerant vaporizes?
pressure / temperature / volume /enthalpy
How can air pressure be changed?
Using the equation P1V1/T1 = P2V2/T2 we find there are two variables we might influence in order to change the pressure of a gas. (P=pressure, V=volume, T=temperature in degrees Kelvin) By increasing or decreasing the temperature of the bottle, you can increase or decrease the pressure within. If the bottle is made of a flexible material, like plastic, you can apply pressure to the bottle. By either squeezing the bottle or increasing atmospheric pressure outside, you deform the bottle and decrease it's volume. Since the quantity of gas inside the bottle is constant, the decrease in volume increases the pressure. Likewise to decrease the pressure in a sealed flexible bottle, you can decrease air pressure outside.
Weather is caused by variations in what three basic ingredients?
temperature, pressure, volume, and density temperature, pressure, volume, and density
If the volume of a fixed amount of gas at constant temperature decreases its pressure does what?
Volume and pressure vary indirectly, which means that when one goes up, the other goes down. If the pressure goes up, the volume goes down. If the volume goes up, the pressure goes down.Mathematically:P1V1 = P2V2The left side represents the beginning conditions, and the right side represents the pressure and temperature that have changed. Note that this formula assumes constant mass and temperature.
How dense is bromine?
Density is derived from a substances mass divided by volume. Density is also related to temperature. The density of pentane at 20 degrees Celsius is . 626 grams per cubic centimeter. Hexane under the same conditions is . 692 grams per milliliter.
Is lead a solid or liquid at 100 degrees?
The melting temperature of a substance is dependent upon the pressure and specific volume. The melting temperature of liquid at standard pressure of 1atm (~100kPa) is 0 degrees Celsius.
If the temperature and volume of a gas changes what else will change?
Volume ChangesThe volume of any solid, liquid, or gas will change with changes in temperature.
What determines the volume of gas?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
What determines a gas's of volume?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
When the pressure on a gas increases at constant temperature its volume?
decreases
What is the volume of 85.1g of acetone?
The volume (at 20 degrees celsius and a pressure of 1 atmosphere) is 107.7mL. Both changes in temperature or pressure will change the answer.
How can you change the volume of a liquid?
- by the variation of the temperature- by the variation of the pressure
It has a definite volume but has no definite shape what is the answer?
A fixed quantity of liquid at a fixed temperature and pressure.
How does the volume of a gas vary?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
What is a STP and VTP?
STP means standard temperature and pressure and VTP means volume temperature and pressure oh and btw standard temperature and pressure is 0 degrees Celsius and 1 atmosphere
The volume of the balloon is 3 liters at a temperature of 300 degrees kelvin What will the volume of the balloon be if the temperature rises to 350?
3.5 litre if pressure is kept constant.
A sample of At gas occupies a volume of 1.2 L at 125 C and a pressure of 1.0 atm. Determine the temperature, In degrees Celsius at which the volume of the gas would be 1.0 L at the same pressure?
A sample of Ar gas occupies a volume of 1.2 L at 125°C and a pressure of 1.0 atm. Determine the temperature, in degrees Celsius, at which the volume of the gas would be 1.0 L at the same pressure.
