What is an open system in enviromental science?
An open system is one that exchanges both matter and energy with its surroundings. For example, suppose Earth is a system and the universe is its surroundings. Earth is an open system, since it can exchange both energy and matter with its surroundings.
Which one of the following conditions would always result in an increase in the internal energy of a system?
the system gains heat and does work on the surroundings
Why does a ball leak air even when it has a tiny hole?
Because the pressure inside the ball is greater then outside the ball. When you poke even a small hole in a ball you connect the ball and the outer surroundings (air) into one system. That system them tries to get toward equilibrium where the pressure is the same in the ball and its surroundings.
What goes cold and then goes hot?
hot on the 19th od April
When a solid changes to liquid will it gain or lose energy?
It looses energy to the surroundings. When bindings brakes, energy is released.
The system adsorbs energy from its surroundings?
An Endothermic change is the system that absorbs energy from its surroundings.
Why is it important to define the system and the surroundings?
You can define a system as part of the universe on which you focus your attention. The surroundings include everything else in the universe. In thermochemical experiments, you can consider the region in the immediate vicinity of the system as the surroundings. A major goal of thermochemistry is to examine the flow of heat between the system and its surroundings.
What is the difference between isolated system and non flow adiabatic system?
An isolated system is a system that doesn't not interact with its surroundings. No interactions at all. No work, no heat transfer. An adiabatic system is one that does not permit heat transfer between the system and its surroundings. It can do work on the surroundings.
What is chemical system?
A chemical system consists of the system and the surroundings. If you're dealing with a solution in a beaker, the solution would be the system and the beaker and air would be the surroundings.

What an open system?
A system that can exchange matter with its surroundings
What is it called when a substance releases energy to its surroundings?
There are two ways that a substance ( called the System ) may release energy to the Surroundings :( 1 ) Heat may be released by heat transfer from the System to the Surroundings. Heat transfer from the System to the Surroundings requires the System temperature to exceed the temperature of the Surroundings and the presence of one or more heat transfer modes ( conduction, convection, and/or radiation.( 2 ) Work done by the System of on the Surroundings corresponding to a force moving through a distance, such as when the substance expands. Substance confined to a cylinder with a piston may expand, doing work on the Surroundings.
An organ system that senses your surroundings is called?
Sensory system.
Does a closed system exchange energy with the outside?
Yes it can... An open system can exchange both energy and matter with its surroundings, where as a closed system CAN exchange energy, but CANNOT exchange matter with its surroundings. Also, an isolated system cannot exchange energy nor matter with its surroundings.
When is a thermodynamic work said to be positive?
In thermodynamics, work done by a system on its surroundings or another system is said to be positive.
What system in which both energy and matter are exchanged with the surroundings is called a?
Closed system
Is flying bird open system or closed system or isolated system according to thermodynamics?
The bird will be best represented as an open system if you include the respiration of the bird and the feathers it drops occasionally. If you neglect those factors you could represent it as a closed system. It will NOT be an isolated system since it does work on its surroundings and its surroundings do work on it - along with some amount of heat transfer from the bird to its surroundings.
