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.

LaoNo, 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.
