w = -P∆V
w = -(1 atm)(0.5 L) = -0.5 L-atm
-0.5 L-atm x 101.325 J/L-atm = 50.7 J
50.7 J x 0.000239 kcal/J x 1000 cal/kcal = 12.1 calories

Atmospheric pressure is the pressure exerted by the atmosphere against the of the earth?
surface.
What does the constant collision of gas molecules against the inside walls of a container produce?
Pressure and heat.
What is the pressure the atmosphere exerts against the surface of the earth?
'Standard' atmospheric pressure is 14 pounds per square inch - or.. one 'bar'.
What is low atmospheric pressure?
Atmospheric pressure is caused by the weight of the air in the earths atmosphere that is above you. At sea level this pressure is said to be 1 bar or one atmosphere. Now, as you go up a mountain there is less air above you and thus the atmospheric pressure is less and the pressure you experience because of your altitude is said to be your local atmospheric pressure. However, the earths atmosphere is heated by the sun and moves in eddies to the poles where it is cooled and flows back to the equator - this is called the weather. When you have hot air above you it is less heavy than cold air so, as the atmosphere blows over you, the pressure of the air changes and you can work out if the air above you is hot or cold by comparing the measure you measure against your local atmospheric pressure.
Why does air pressure becomes lower as water molecules are added to the air?
Air pressure is the weight of the air at a specific location. On the surface of the earth, we have the entire weight of the atmosphere pressing on us in the form of air molecules like O2, N2, and CO2. As we go higher and higher into the atmosphere, there are fewer molecules and so there is less weight pressing against us.
Atmospheric pressure is the pressure exerted by the atmosphere against the of the earth?
surface.
What does the constant collision of gas molecules against the inside walls of a container produce A Temperature Bdensity C Pressure Ddiffusion?
The constant collision of gas molecules against the inside walls of a container produces pressure which is directly proportional to the number of collisions.
What does the constant collision of gas molecules against the inside walls of a container produce?
Pressure and heat.
What does barometric pressure have to do with evaporation?
Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.
How is pressure made?
Pressure is simply the constant bombardment of atoms against a container's wall. The hotter the substance inside the container, the faster the atoms are moving, thereby making the pressure increase.
How does higher altitude have an effect on pressure?
The higher you go into the atmosphere the less particles are present, because of gravity, so you have less particles pressing against you (pressure).
Which symbol in the first law of thermodynamics represents a result of a gas expanding against a constant pressure?
its the one that looks like a w
What is the pressure the atmosphere exerts against the surface of the earth?
'Standard' atmospheric pressure is 14 pounds per square inch - or.. one 'bar'.
One ATM equals standard ATMospheric pressure at sea level Choose the correct measure of one ATM?
Atmospheric pressure refers to the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. The standard atmosphere (symbol: atm) is a unit of pressure at sea level and is equal to 101325 Pascal.
What is the lowest pressure against the walls of the blood vessels?
No, systolic pressure is the highest pressure against the walls of the blood vessels. Diastolic pressure is the lowest pressure against the walls of the blood vessels.
A sentence using the word granulating?
Rivers have a granulating effect on stone - the pressure of the water and the constant motion of stones against one another gradually reduces stone to sand.
How much work does a gas do when it expands against a constant pressure of 0.500 ATM from a volume of 50.00Â mL to a volume of 350.00 mL?
Without actually doing your homework for you ... have you noticed that if you multiply pressure by volume you get the exact units used for work?
