Answer:
Explanation:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Answer: it involves a change in physical properties, such as melting, condensing, evaporating, change of color, shape, size, volume an density
out onto the rear seats. Why does this happen?
Answer:
See the explanation below
Explanation:
This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.
Answer:
This happens because of inertia.
Explanation:
Inertia is the ability of a body to remain in its state of rest or relative movement, while an external force is not acting on it.
It is when a body objects to modifying its state of relative rest or movement, including the speed and direction in which this happens.
When a car accelerates, a cup of coffee sitting in a cup-holder spills out onto the rear seats, because it has left its state of rest due to the acceleration force of the car.
