A monatomic ideal gas at a pressure of 2x105pa expands at a constant temperature from an initial volume of 3.00m3 until its volume doubles. How much work is done on the environment?
W=P(Vf-Vi) W=(2x10^5pa)*(6.00m^3 - 3.00m^3) W=6x10^5 pam^3 But 1 pascal is equal to 1 (Newton)/(meter^2) W=6x10^5 Nm=6x10^5 Joules
Why does a helium tank get colder as you let out more helium?
Letting gas out of a cylinder always causes a cooling. This is the Joule-Thomson effect. As the gas expands work is done against the interatomic/molecular attractions (dispersion forces for helium).
What quantity is the sum of the kinetic energy and all forms of potential energy in a system?
the total energy U. If there is no work done on the system, Uint= KE+PE
Why don't you do any work when you carry an object art a constant velocity?
Well, if you do that for a while, you could certainly raise a sweat, and you would say that you've done a lot of work. But in the strict Physics definition of "work", none of it has been done to the object you carried. The strict definition is: Force acting through a distance. Referring to the object you carry: -- You don't move it vertically. You just hold it there against the force of gravity, but your vertical force doesn't move it up or down. So no work is done vertically. -- Horizontally, the speed is constant. No force is required to maintain a constant speed, so no work is done horizontally either.
How is the pressure and absolute temperature of a gas at constant volume related?
It is change in internal energy. If the volume of the system remains unchanged (isochoric process)then the heat given to the system is entirely utilized to increase the internal energy of that system. It is to be noted that no pressure-voulme work is done in such processes.
When an ideal gas expands in vacuum work done is?
work done is zero when gas expands in vacuum.sarin madhusoodanan
When a gas expands to a region of low pressure what happen to its temperature?
The temperature drops. When a real (non ideal) gas expands ( in such a way that it does not take in heat from the environment- so called adiabatic) for example when hot air rises into a low pressure region the gas will cools. Real gases when they expand freely cool, this is the basis of the refrigerator (Joule Thomson effect). The explanation is that the separation of gas molecules involves "work" done against intermolecular forces which leads to a reductio in the kinetic of the molecules, hence the observed temperature.
What is the constant part in a science project?
The constant part or the constant variable is the thing that isn't changed throughout your entire experiment.There are different parts of a project. The parts of a project is what is to be done, when it needs to be done, who does it and how will it be done.

Why they are putting marks in exam?
In an exam, each parson's paper is marked and points awarded against an "ideal" answer. The number of marks awarded show how well a person has done in answering the exam questions.
What is the work done when a force of 20N moves a book 3.5M what is the potential energy?
The idea is to multiply force times distance. This assumes that both are in the same direction, and that the force is constant. If the force is done against a gravitational field, or some other so-called "conservative force", then all the work done will be converted to potential energy. If it is done against friction, the work is basically wasted. It is converted to heat, and NOT to potential energy.
Work is done when a force is used to?
Work is done when force is used to be approximately constant
What organ expands to fill with air?
Lungs expand to fill with air. It is done during respiration.
Is the work-done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
