How many air molecules are in a 13 x 12 x 10ft room Assume atmospheric pressure of 1 00 ATM a room temperature?
To solve this problem, several different steps must be taken.
Convert Volume = 13*12*10 = 1560ft^3 * 28.2 = 43992L ~28.2 Litres per cubic ft
Ideal Gas Equation: PV=nRT Rearrange: n=PV/RT Temperature:273+20=293K
n=[(1*43992)/(0.0821*293) = 1828.78
1 mol Air Molecules = 6.022*10^23 Air Molecules
1828.78*(6.022*10^23) = 1.10 * 10^27

What is the approximate temperature of Naos?
Uhh, Are you doing this on a gizmo from explore learning? If so, and it's telling you what do you THINK, you can only understand from the clues you are given. If you have this question, "Infer: Naos is a star in the Argos constellation. It has a very deep blue color. What do you think is the approximate temperature of Naos?", then I will share my thoughts about it so you understand it more. On the gizmo, the highest temperature on the graph given to us is 50,000 K, and the question is telling us that the color of the star is a very deep blue color. With this, we can assume it has a very high temperature and would be close to the highest temperature given. I hope this makes sense, I'm not very good at explaining my thought process.
The diagonals of a square?
Yes, they do exist. I assume that was the question!
How many calories of heat are needed to raise the temperature of 24.0g of diethyl ether from 9.0 C to 30.0 C?
Assume the specific heat of diethyl ether to be s cals/gm If the ether does not change states and does not burn going from 9.0C to 30.0C, then the number of calories required to heat 24g through this temperature range would be 24 x s x (30-9) = 24 x s x 21 = 504s cals
Why does vapor pressure increase with an increase in temperature?
Vapor pressure is the pressure exerted by gas molecules when they escape from a liquid. When the temperature increases, the average kinetic energy of the liquid molecules also increases, causing more molecules to have the energy to escape and become vapor. As a result, the vapor pressure increases with temperature.
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
The boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure. At this point, bubbles of vapor form within the liquid, leading to a phase change from liquid to gas.
What measures the atmosphere?
The atmosphere is measured using various instruments such as weather balloons, satellites, ground-based stations, and aircraft. These instruments measure different aspects of the atmosphere, including temperature, humidity, pressure, and composition. Data collected from these measurements helps in monitoring and understanding atmospheric conditions.
How do you convert a differential pressure of 43 psi to absolute units?
To convert the differential pressure of 43 psi to absolute pressure, you would add the atmospheric pressure to the differential pressure. On average, atmospheric pressure at sea level is about 14.7 psi. So, adding 43 psi to 14.7 psi gives an absolute pressure of approximately 57.7 psi.
If 3750 liter of air must be compressed into a 26 liter tank what will be the final pressure of the air in the tank?
assume that the air is originally at atmospheric pressure
How does atmospheric pressure affect the melting point of a liquid?
I assume you mean melting point of a solid (if it's liquid it has already melted). It decreases as you increase the pressure.
Why a helium weather balloon expands as it rises in the air. assume that the temperature remain constant.?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.
Why does the vapour pressure of water contribute to the total pressure in the bottle?
The vapor pressure of water in the bottle adds to the total pressure because it represents the partial pressure of the water vapor molecules in the gaseous phase in equilibrium with the liquid water. This means that the water vapor exerts a pressure that contributes to the overall pressure inside the bottle alongside other gases present.
What is the melting point of an element?
It is the temperature at which the element will change state from a solid into a liquid. Note that the temperature actually changes depending on pressure. When no pressure is given assume 1 atmosphere.
When can you safely assume any gas is ideal?
You can safely assume a gas is ideal when the pressure is low, the temperature is high, and the gas particles do not interact with each other. Additionally, the volume of the gas should be large relative to the size of the gas particles.
The temperature at which a substance changes from its solid state to its liquid state?
The freezing point. This is unique to the material you are talking about, and must be looked up in a table or a chemistry book or online. Water changes at 0 degrees Celsius, which is 32 degrees Fahrenheit, if you are at normal atmospheric pressure (1 ATM). If they don't tell you what pressure you are at, you can assume 1 ATM (one atmosphere, normal outside air pressure)
When a sealed bag is compressed does the air pressure decresssed?
Assume temperature remains constant, then the pressure will rise in proportion to the decrease in volume, and vice versa.
