An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
WebJan 30, 2024 · Energy is measured in terms of its ability to perform work or to transfer heat. Mechanical work is done when a force f displaces an object by a distance d: (1) w = f × … Webthermodynamics, science of the relationship between heat, work, temperature, and energy.

WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy.
