The definition is that work is done when a force moves through a distance. Heat has to be removed from water to make it freeze (even if it starts as water at 0 degrees and ends as ice at 0 degrees) but no actual work is done in the process.
However, because the water expands when it turns into ice some of it moves slightly. Therefore a small amount of work is, in fact, done.
No, work is not being done when water freezes into ice. The transition from water to ice is a physical change that releases heat energy, resulting in a more ordered state with lower energy. Work is defined as the transfer of energy that results in a change in an object's state or motion.

How does frost wedging work?
Frost wedging occurs when water seeps into cracks in rocks, freezes, and expands. The expansion of the ice exerts pressure on the surrounding rock, causing the crack to widen and eventually break apart. This process repeats with each cycle of freezing and thawing, eventually leading to the disintegration of the rock.
How does water work to cause mechanical weathering called frost wedging?
Water enters cracks in rocks, freezes, and expands. As it expands, the ice exerts pressure on the rock walls, widening the crack. When the ice melts, the crack remains widened. Over time, repeated freeze-thaw cycles can cause the rock to fracture and break apart, a process known as frost wedging.
How does water and temperature work together to cause weathing?
Water and temperature interact to cause weathering through a process called thermal expansion and contraction. When water freezes, it expands, putting pressure on surrounding rocks and causing them to crack. As temperatures rise, rocks expand and contract, leading to further weathering and breaking down of rocks. Additionally, water can seep into cracks in rocks, freeze, expand, and break the rocks apart through a process known as frost wedging.
Dimensional formula of work?
The dimensional formula of work is given by [ML^2T^-2]. It is expressed in terms of mass (M), length (L), and time (T).
What is the difference between capacity and load?
The difference between load and capaity is as follows:Load is the amount of work that MUST be done, amount of work scheduled ahead of a manufacturing facility.Capacity is the amount of work that CAN be done, and measures the highest output of work expressed as a rate with current product specifications, work force, plant, equipment etc.
How do you know work is being done?
work is being done when you use energy
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
Is When a person swims through water no work is done true?
No, this statement is not true. When a person swims through water, work is being done because the person is exerting a force to move their body through the water against resistance. Work is calculated as force multiplied by distance, so swimming does involve work.
If an object is being pushed but does not move is there any work being done on the object?
No, work is only done on an object when there is displacement in the direction of the force applied. If the object does not move, then no work is being done on it.
How Describe a situation in which work id done in object.?
An example of work being done on an object is when a painter paints a canvas. The canvas is the object on which the work of painting is being done. The action of applying paint to the canvas is the work being performed on the object.
How does a book work?
work can only be done by a living being
What does Lab work means?
It is work that is being done in a laboratory.
Can you help me with my home work need info for why does food freeze?
food freezes because it contains water,or a liquid.
When you do laundry is work being done?
Yes it is.
How do you know when work is being done?
you know when work is done when it's finished and checked and approved by someone.
Is work being done when someone is typing a letter?
Yes it is being done, if the person doing it is doing it as part of a paid job or because they run a business and the letter is needed for the business. If it is being typed for school it may also be considered work, but of a different kind. And from the view of physics, since energy is being expended by the person typing, and perhaps by the machinery being used, work is being done. However, if you are at work and typing a letter to your grandmother, that is not the kind of work you are being paid for and your employer would say work is not being done.
Is work being done when you lift a box?
Yes, work is being done when you lift a box against the force of gravity. Work is defined as the force applied over a distance, and in this case, the force you exert to lift the box is acting over a vertical distance, thus work is being done.
