What else can I help you with?
A sample of gas in a syringe releases heat go its surroundings while the plunger us pulled out what are the correct signs of heat and work in this change?
In this scenario, the gas is doing work on its surroundings, so the work is negative. Since heat is being released from the gas to its surroundings, the heat is also negative. The sign convention typically defines work done by the system as negative and heat released from the system as negative.
How do you calculate the molar volume of a substance?
To calculate the molar volume of a substance, you divide the volume of the substance by the number of moles present. This can be done using the formula: Molar Volume Volume / Number of Moles.
How can one calculate the work done during an adiabatic reversible expansion process?
To calculate the work done during an adiabatic reversible expansion process, you can use the formula: work -nRT ln(V2/V1), where n is the number of moles of gas, R is the gas constant, T is the temperature, and V1 and V2 are the initial and final volumes of the gas.
How do you calculate the total volume of a solution?
To calculate the total volume of a solution, you add together the volumes of all the individual components in the solution. This can be done by measuring the volume of each component separately and then adding them together to find the total volume of the solution.
What is the process to calculate the delta H for the reaction?
To calculate the change in enthalpy (H) for a reaction, you need to subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This can be done using Hess's Law or by using standard enthalpy of formation values.
Expansion happens because?
there is too much pressure in a system. example, a system which has done work and releases heat will expand itself
What is the formula to calculate the total work done in a system?
The formula to calculate the total work done in a system is W Fd, where W represents work, F is the force applied, and d is the distance over which the force is applied.
How to calculate the work done by friction in a given system?
To calculate the work done by friction in a system, you can use the formula: Work Force of friction x Distance. First, determine the force of friction acting on the object. Then, multiply this force by the distance the object moves against the frictional force. This will give you the work done by friction in the system.
How do you calculate the steady state of a system?
To calculate the steady state of a system, you need to find the point where the system's behavior remains constant over time. This is typically done by setting the rate of change of the system's variables to zero and solving for the equilibrium values.
What is the adiabatic work equation used to calculate in thermodynamics?
The adiabatic work equation 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 represented by the formula W -U, where W is the work done, and U is the change in internal energy of the system.
What is the delta U equation and how is it used to calculate changes in internal energy?
The delta U equation is U Q - W, where U represents the change in internal energy, Q is the heat added to or removed from the system, and W is the work done by or on the system. This equation is used to calculate changes in internal energy by considering the heat transferred to the system and the work done on or by the system.
What is the meaning of Perpetual and periodic system of accounting?
Perpetual System is that system in which company continuously updates the value of inventory while in periodic system inventory valuation is done only for closing inventory when company done physical inventory calculation.
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 do you calculate the internal energy of a system?
The internal energy of a system can be calculated by adding the system's kinetic energy and potential energy together. This can be done using the formula: Internal Energy Kinetic Energy Potential Energy.
Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as Negative
How do you calculate work done on an object .?
The equation to calculate the work done is: Work done (J) = force applied (n) x distance moved of force (m)
Why do you feel the effects of marijuana but haven't done any of it?
if you are not near someone who is smoking it to get whats known as a contact hi, then the only other reason you would feel the effects of it is when your detoxing off of it or have not done it in a while an its seeping out your system, like that's why it takes so long to get a clean urine after using it, because it stores in your fat cells an releases little by little over the next 4 weeks. so while releasing it may give you the feeling of using again
