∙ 9y agoIt is -340.368 Joules.
The formula is: w=-P*change in volume=-1.2atm*2.8L=-3.36L*atm
Then convert the units-- 1L*atm=101.3J

∙ 9y agoThe function of the bulb of a manual sphygmomanometer is to inflate the cuff to stop the flow of arterial blood in the arm so that the blood pressure can be determined. The bulb pumps air into the cuff, causing it to expand against the upper arm. Enough air is pumped into the cuff to stop the flow of arterial blood. The pressure is then slowly released and the point at which blood begins to flow again is recorded as the systolic pressure, representing the highest arterial pressure of the cardiac cycle. Blood flows only with the beating of the heart, however, and further pressure is released until the arterial blood flows freely. This point is recorded as the diastolic pressure, representing the lowest arterial pressure when the heart is at rest.
Expand generally means to expand the problem. I'm assuming this is a function, you'd expand it into a simpler form (factor things out and such).
Vehicles ove forward because of friction between the tyres and the road. Friction causes heat so the tyres and the air inside them heat up. A confined gas (air) tries to expand when it is heated. Tyres will expand, when the air inside applies sufficient pressure.
get bigger or expand you can pick which one you want to try get bigger or expand
24000 = 20000 + 4000 in expand form
The balloon would heat up and expand as the air inside it warms up. If the temperature exceeds the balloon's capacity, it could burst.
As the external pressure drops with increasing altitude, balloons generally expand with height.
The balloon would expand due to the lack of atmosphere on the moon, but it wouldn't burst because the pressure inside the balloon would equalize with the low pressure outside. Additionally, the balloon would float in the lower gravity environment of the moon.
The ideal gas law states that as altitude increases, air pressure decreases. This lower pressure causes the bag of chips to expand because there is less external pressure pushing on the bag. The gases inside the bag expand to fill the increased volume.
The plastic ball will remain in the container unless moved or acted upon by an external force. It will not change its state unless there is an external influence such as another object pressing against it or a change in temperature or pressure causing it to expand or contract.
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.
because you're putting pressure inside the tire of the required psi recommended
Normally a leak in the sytem, either internal or external. More details would be required to expand on the answers to be given
Air expand on heating as heat in a gas is the random kinetic energy of the molecules. Pressure is the result of kinetic energy in one direction, so an increase in heat leads to an increase in pressure, which leads to expansion against the surroundings.
Heating the air inside the balloon causes the air molecules to move faster and spread out, increasing the pressure inside the balloon. This increase in pressure pushes against the balloon's walls, causing it to expand and inflate.
Blowing air into the balloon increases the pressure inside the balloon. This increased pressure pushes against the walls of the balloon, causing it to expand and stretch. The volume of the balloon increases, allowing it to hold more air.
When CO2 is added to a balloon, it has a higher pressure compared to the surrounding air. This pressure difference causes the balloon to expand because the air inside is pushing against the walls of the balloon more forcefully than the air outside.
