How does the relationship between pressure, volume, and work manifest in the context of thermodynamics?
In thermodynamics, the relationship between pressure, volume, and work is described by the equation: work pressure x change in volume. This means that when pressure increases or volume decreases, work is done on the system, and when pressure decreases or volume increases, work is done by the system. This relationship helps to understand how energy is transferred and transformed in thermodynamic processes.
What is the product of pressure times volume?
The product of pressure times volume is equal to the work done on a gas. This relationship is described by the ideal gas law equation, which states that pressure multiplied by volume equals the number of moles of gas, the gas constant, and the temperature of the gas.
How can the relationship between enthalpy change (H), internal energy change (U), and pressure-volume work change ((PV)) be expressed in a single equation?
The relationship between enthalpy change (H), internal energy change (U), and pressure-volume work change ((PV)) can be expressed in a single equation as: H U (PV).
How do you work out the volume of gas?
To calculate the volume of a gas, you can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin. Simply rearrange the equation to solve for V given the other variables. Alternatively, if the gas is at standard temperature and pressure (STP), you can use the molar volume of a gas at STP, which is 22.4 L/mol.
What is the adiabatic work formula used to calculate in thermodynamics?
The adiabatic work formula in thermodynamics is used to calculate the work done on or by a system when there is no heat exchange with the surroundings. It is given by the equation: W -PV, where W is the work done, P is the pressure, and V is the change in volume.
Can you work out pressure from volume?
No. For a gas, temperature also comes into the equation.

How does Boyles law work?
1. A more correct name is Boyle-Mariotte law. 2. This law is a relation between pressure and volume at constant temperature. The equation is: pV = k where p is the pressure, V is the volume, k is a constant specific for the system.
How can you make the pressure of air less than normal?
Well the easiest answer I can think of is to use the ideal gas equation and look at the terms and their effect on pressure. PV=nRT == P=(nrRT)/V, as can been seen from the equation: Pressure is directly proportional to Temperature and inversly proportional to Volume. So you trap air inside a fixed volume container. (Note: not every container will work. The walls of the container must be able to withstand the imbalance between the new inner air pressure and the atmospheric pressure.) Then simple cool the container. If you have gauge fixed to the rigid container (measuring the interior) you will see a drop in air pressure inside the container.

How is pressure volume equal to a joule?
In the context of thermodynamics, work done on a gas can be calculated using the formula W = PΔV, where P is pressure and ΔV is the change in volume. Since work done is measured in joules, pressure multiplied by volume change gives the work done in joules.
How do you work out volume of compressed air?
To calculate the volume of compressed air, use the ideal gas law equation: PV = nRT, where P is the pressure of the compressed air, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature. This formula allows you to calculate the volume of the compressed air if you know the pressure, temperature, and quantity of air.
What is the adiabatic work formula used to calculate in thermodynamics?
The adiabatic work formula in thermodynamics is used to calculate the work done on or by a system when there is no heat exchange with the surroundings. It is given by the equation: W -PV, where W is the work done, P is the pressure, and V is the change in volume.
How much work does a gas do when it expands against a constant pressure of 0.500 ATM from a volume of 50.00 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?
What it the State of a gas when its volume increases and its pressure decreases?
When the volume of a gas increases and its pressure decreases, the state of the gas is expanding. This typically occurs when the gas is allowed to do work by pushing against a piston, which results in an increase in volume and a decrease in pressure.
