Tearing a piece of paper is a physical change.
It takes a large amount of force to remove the piece of paper stuck on the end of the vacuum hose because of the suction force created by the vacuum cleaner. The paper is being held in place by the pressure difference between the inside and outside of the hose, making it difficult to remove. Additionally, the paper may create a seal around the end of the hose, increasing the force needed to break that seal.
The time it takes to burn a piece of paper with a magnifying glass depends on various factors such as the intensity of the sunlight, the distance between the magnifying glass and the paper, and the type of paper. Generally, it can take a few seconds to a couple of minutes to start a fire on the paper using a magnifying glass.
The change in position divided by the time interval is known as velocity. Velocity is a vector quantity that specifies the rate of change of position of an object in a particular direction.
yes paper is matter
The time it takes to make paper varies depending on the method and equipment used. On average, it can take anywhere from a few hours to a few days to complete the papermaking process, including pulping, drying, pressing, and cutting the paper into sheets. Industrial paper mills can produce paper more quickly than handmade paper studios.
Yes it's a physical change. No new substance is formed,
The yellow color is changed to green and then in blue.
A change of phase takes place at a constant temperature.

I assume you mean chemical "change" and the answer is no, it is a physical change that takes place.
It takes a lot of water to change wood chips into paper. It takes much less water to make paper out of recycled paper. It's a much easier process.
Mrs. Clark can determine the total number of pieces of paper by dividing the total mass of paper by the mass of one piece of paper. In this case, if a single piece of paper weighed 20 g and she cut it into quarters, each quarter would weigh 5 g. Therefore, she knows that there are four pieces of paper in total.
The newly promoted piece takes up the same square where the promotion occurred .
a chemical change take a place
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.
In evaporation, the surface of the water begins to change from a liquid to a gas.
