Difference between a physical change and a chemical change?
A chemical change is the change of one or more substances into other substances. A physical change is when the state or shape of matter is changed. In a chemical change molecules are combined or beak apart to form new substances.Rusting iron is an example of a chemical change. crushing a can or tearing paper can be an example of physical change.
What are some differences of physical weathering and chemical weathering?
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
What are non-examples of mechanical weathering?
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
How can minerals be identifed by their physical properties?
Yes
Is crushing a rock chemical or physical change?
Grinding something is an example of a physical change, because you are not chemically changing what the substance is, you are only changing the form of it. Another example of a physical change is boiling water, because the water is still water, it's just in a gas form instead of liquid.When something is grinded it is a physical change not a chemical change.
What type of physical change will while crushing a rock and burning a candle?
1. Crushing is a physical process.2. Burning is a chemical process.
Is crushing rocks a physical change?
Yes, crushing rocks is considered a physical change because the rocks are broken down into smaller pieces without changing their chemical composition. This process can be reversed by reassembling the pieces back together.
Is grinding salt a chemical or physical change?

When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
Is rock broken into small pieces a chemical change?
No actually it isn't. Breaking a bone is a physical change. Think about it. Are you changing it into a different substance. No you're not, so it's a physical change.
Is a rock getting melted into magma a chemical reaction?
No, the process of a rock melting into magma is a physical change, not a chemical reaction. The change is due to an increase in temperature causing the rock to undergo a phase change from solid to liquid.
What are effects of physical and chemical change on health and environment?
rock
Is landslide physical or chemical change?
Physical. It is still dirt/rock, no change to it's nature- just its position.
Is making a rock candy by evaporating water from a sugar solution a physical or chemical change?
physical
If crushing a rock is a physical change what type of change does buring a candle create?
Burning a candle is a chemical change, as it involves a chemical reaction where the wax and oxygen combine to produce carbon dioxide, water vapor, and energy in the form of heat and light. This change is irreversible and creates new substances.
