In summary, the conversation discusses a problem involving a piston filled with N2 gas and the heat added to it, leading to a temperature and volume change. The value of ΔE is also mentioned, and the question of what external pressure the gas is expanding against is raised. The conversation also mentions two processes that consumed the added heat and asks for the calculation of the energy used by each process.

Can someone help me with this problem? Even if you could just tell me the steps I'd need to take.. or even just an equation. Something please?

A piston filled with 21.9 of N2 g (MW = 28.02 g/mol) has an initial volume of 7.27 L. 849.5 J of heat were added to the piston, which increased the temperature of the gas by 37.3 °C, leading to a volume change of 0.839 L. The value of ΔE for this expansion process was 607.2 J. What external pressure is this gas expanding against? (The specific heat of N2 g is 1.04 J/g °C)

Added heat was consumed by two processes. Can you name them? Calculate how much energy each of the processes used?

FAQ: What External Pressure Is This Gas Expanding Against?

What is external pressure?

External pressure refers to the force per unit area exerted on an object by its surroundings. This can include atmospheric pressure, water pressure, or any other type of force acting on the object from the outside.

How can external pressure affect an object?

External pressure can cause an object to compress, expand, or deform depending on the material and strength of the pressure. It can also cause changes in the object's density, volume, and temperature.

What are some common examples of external pressure problems?

Some common examples include the pressure exerted on a submarine or deep-sea diving equipment by water, the pressure on a plane's surface during flight, and the pressure on a building's walls from wind or earthquakes.

How do scientists calculate external pressure?

Scientists use mathematical equations, such as the hydrostatic equation, to calculate external pressure based on factors such as depth, density, and gravity. They may also use specialized instruments, such as pressure gauges, to measure and record external pressure.

How can external pressure problems be solved or managed?

Solving or managing external pressure problems often involves understanding the properties of the object and its surrounding environment. This can include designing structures to withstand certain pressures, using materials that can withstand high pressures, or using technology to equalize pressure differentials.
