What else can I help you with?
Does density change if the sample of the same matter is larger?
No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
What happens to sample of matter when its particles lose kinetic energy?
its particles stop moving around because of loosing kinetic energy. As you know kinetic energy is something that moves around .And particles in sample of matter cool off and stop.
What is a measure of the pull of gravity on a sample of matter?
Weight is a measure of the pull of gravity on a sample of matter. It is the force acting on an object due to gravity and is typically measured in units such as pounds or Newtons.
What term is defined as a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is defined as a measure of the average kinetic energy of the particles in a sample of matter. It indicates how hot or cold an object is.
What is the Quantity of matter in an object or sample?
The quantity of matter in an object or sample is typically described by its mass. Mass is a measure of the amount of matter in an object and is often expressed in units such as grams or kilograms. It is different from weight, which is the force exerted on an object due to gravity.
What does not change when a physical change in a sample occurs?
Substance in the material Remain the same
Is melting a sample of gold an example of a physical or chemical change?
Melting a sample of gold is an example of a physical change.
Is freezing biological samples for storage a chemical or physical change?
It is a physical change. Any change in state or temperature is only physical unless it causes the atoms in the molecules to separate or rearrange themselves. In the case of freezing a biological sample, the point is to preserve it as it is, so the change would only be physical.
How will identifying if a property is chemical or physical?
A physical property can be observed without changing the sample. Chemical properties requires you to change the sample.
What phase change occurs as the temperature of the sample at 3 ATM is raised from -90ºC to -50ºC?
This depends on the type of sample.
What is Sample of physical change?
A sample of a physical change is when ice melts into water or a piece of paper is torn into smaller pieces. These changes do not alter the chemical composition of the substance, only its physical state or appearance.
Is stone is a sample of matter?
Yes, stone is a sample of matter. Matter is anything that has mass and takes up space, and stone fits this definition. It is made up of atoms and molecules that give it its physical properties.
What makes a sample of a matter homogeneous?
A sample of matter is considered homogeneous when its composition is uniform throughout, meaning the components are evenly distributed at a molecular level. This results in consistent physical and chemical properties in all parts of the sample.
What is the property of a substance no matter whether the sample is large or small?
It is the behaviour exhibited by matter in various chemical, physical or biological reactions or treatments.
Is destiny extensive or intensive physical property?
Density is an intensive property because the size of the sample does not matter.
What can be observed only when the substances in a sample of matter are changing into different substances?
chemical change
What property of matter changes depending on the gravitational pull?
Weight
