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.
When system does work what happens to it's internal energy?
When a system does work on its surroundings, its internal energy deceases. This is because some of the internal energy of the system is being used to perform the work.
What is a system which can exchange both matter and energy with its surroundings?
An open system is one that can exchange both matter and energy with its surroundings. This allows for a continuous flow of materials and energy in and out of the system, enabling it to maintain its internal balance despite changes in the surroundings.
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10 2 kJ of work on the system What is the change in internal energy of the system?
3.0 x10 1 kj A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10³ kJ of work on the system. What is the change in internal energy of the system? --- 224 kj
Why does temperature of gas drops in an adiabatic process?
In an adiabatic process, no heat is exchanged between the system and its surroundings. When a gas expands without heat input, the gas does work on its surroundings and loses internal energy, leading to a decrease in temperature.
What is different between internal and external?
Internal is inside the organism External is the surroundings and stuff that happens outside the organism

A 19 V battery delivers 114 mA of current when connected to a 72 resistor. Determine the internal resistance of the battery.?
Internal resistance is approximately equal to 94.667
A 4.8 V battery cell delivers a current of 3 A through an external resistance of 1.2 Ohms Calculate the internal resistance in Ohms?
4.8 / (1.2 + R) = 34.8 = 3 (1.2 + R)4.8 = 3.6 + 3R1.2 = 3R0.4 ohm = R
What happens to the internal energy of a gas when it expands?
When a gas expands, its internal energy typically increases. This is because the gas is doing work on its surroundings as it expands, which results in an increase in its internal energy.
What is the change in the internal energy of a system that absorbs 2.500J of heat and that does 7.655J of work on the surroundings is?
The change in internal energy is the sum of heat added to the system and work done by the system on the surroundings. So, the change in internal energy is 2.500J (heat absorbed) - 7.655J (work done), resulting in a change of -5.155J.

Define output unit?
In computers, a unit which delivers information from the computer to an external device or from internal storage to external storage
If a 12v car battery has 0.04ohm internal resistance what is the battery terminal voltage when the battery delivers 40A?
011.1

What happens when a warmblooded animal is cold?
Endothermy (the state of being warm blooded) is not absolute. A warm blooded animal is an animal that has some ability to keep its internal body temperature constant, but extreme outside temperatures can overpower this ability. If a warm blooded animal is in cold enough surroundings, it will fail to keep its internal temperature constant. It will develop hypothermia, and may freeze to death. If its surroundings are not quite as cold, it will probably be able to keep its internal temperature constant, as long as it eventually enters warmer surroundings (or its present surroundings warm up).
