A weather balloon is filled with helium that occupies a volume of 3.35 104 L at 0.995 ATM and 32.0C After it is released it rises to a location where the pressure is 0.720 ATM and the temperature?

9000 / 101325 =0.977 atm
n = 2.4 x 10^2 x 0.977 / 0.08206 x 273 K=10.5 moles He
mass He = 4.0 x 10.5 =42 g

∙ 14y agoWhat is it you are trying to find: the temperature outside the balloon's new location? or could it be the volume the gas now occupies? Also, for clarification, is the inital volume 3.35104 L?

A balloon carrying weather instruments is released at Earth?
Temperature, Pressure, and humidity.
WILL liquid co2 boil at room temperature?
CO2 will not be a liquid at room temperature, rather a gas. It is only a liquid when compressed. Actually IF contained at high pressure it will be a liquid at room temperature ...It requires a combination of both pressure and temperature. It is a liquid in CO2 fire extinguishers and when the pressure is released some of it boils, absorbing a large amount of heat energy, more of it is released from the nozzle as a solid which then sublimes to forma gas.
How does density temperature and pressure change as you move on the lithosphere to the inner core?
It gets hotter and more pressure is released because the inner core is a solid layer .
What happens when Carbon dioxide gas is compressed at room temperature and the pressure is suddenly released?
When carbon dioxide gas is compressed at room temperature and the pressure is suddenly released, it undergoes a process called adiabatic expansion. This leads to a rapid decrease in pressure and a decrease in temperature as the gas expands. Sometimes, this sudden decrease in temperature can cause the gas to condense into a solid or a white mist.
Does seltzer in water make the temperature rise?
No, adding seltzer to water does not raise the temperature. Seltzer is simply carbonated water, which means it contains carbon dioxide gas dissolved under pressure. When the pressure is released, the gas comes out of solution as tiny bubbles, but this does not result in a temperature increase.

Temperature, Pressure, and humidity.
What happens to gas pressure when temperature rises?
If the volume remains constant, the pressure will increase as the temperature increases. In an ideal gas (under normal conditions, gases have a behavior that's close to that of an ideal gas), the pressure is directly proportional to the temperature. Assuming, of course, that the temperature is measured in Kelvin.

What is flashsteam?
Flash steam is steam that is produced when high temperature high pressure water is released to the atmosphere.
Why does the liquid in a butane lighter become gas after being released?
It's the pressure in the lighter that keeps the butane liquid. When released into the atmosphere, under room pressure and temperature, returns to it's state of gas.
Why does ice form around a container when gas is released?
With gasses, it's a three-way balance between pressure, temperature and volume. If you change one, you affect the other. When you release gas from a container, the the pressure and the temperature drops.
How does density temperature and pressure change as you move on the lithosphere to the inner core?
It gets hotter and more pressure is released because the inner core is a solid layer .
How do temperature pressure and fluid content affect the formation of magma?
The air affects magma. Once magma is released above ground, called lava, the air hardens it. While it is underground, the higher the temperature and pressure, the runnier the magma.
Do the pressure of a gas decreases with increasing temperature?
If the temperature remains constant, decreasing the volume will increase the pressure.
How does a thermal expansion valve work?
If you are talking about a temperature and pressure valve on a water heater (pop off valve). It is controlled by spring pressure and a rubber seal. As pressure in the tank increases the tension exerted by the spring on the rubber seal is over come until the point at which excess pressure is released around the rubber seal. When the pressure inside the tank decreases the spring again pushes the rubber seal closed. Temperature of the water in the tank is directly related to the pressure.. higher temperature = more pressure.

A helium-filled balloon occupies a volume of 15 cubic meters at sea level The balloon is released and raises to a point in the atmosphere where the pressure is 75 ATM What is its volume if the te?
75 atmospheres of pressure is 1125 pounds per square inch. A balloon would be unlikely to withstand this pressure.
