Mass is related to weight, but the two are not identical. Mass measures the quantity of matter in an object. As long as the oblect is not changed, it will have the same mass, no matter where it is in the universe. On the other hand, the weight of that object is affected by by its location in the unvierse.

How is mass different than weight is a measure of the gravitational force exerted on an object its value can change with the location of the object in the unitverse and mass is a measure of the amount of matter in an object a fundamental property of an object that is not affected by the forces that act on the object, such as the gravitattional force.

2day i learned about sigfigs and how 2 count them

what i learned today about the sig figs are that a 0 before a decimal dont count and a zero behind the decimal does count.

What I've learned about sig. fig. is that it uses four rules to desrcibe how many nunbers are there. Also how if the 0 is on the other side of the decmial the zero isnt a sigfig number.

well today i learned the rules number 1 -4 ..an how to tell sig numbers from non sig numbers...

If the number zero is to the left then the zero does not matter.

I learned about chemical,physical changes and whatg they do and i also leaned about the sigfig and how to do it and took notes about chapter one..

i learned about the states of matter and that physical changes don't change an object completely.

Physical change are changes in which the idenity of a substances doesn't change and chemical change occur when the identities of substances change and new substances form together.

A chemical change is a change tht occurs when one or more substances form a new substance.A physical change is a change of matter from one form to another without a change in chemical properties.

The difference between physical & chemical reactions is chemicals have to with liquids & physical is like a solid change.

The difference between physical change and chemical change is that physical change is the identity of a substance that doesnt change. Chemical Change is when identities of substances change and new subtances form.

physical changes are changes that dont affect the identity of a substance.however,chemical changes are changes that can change the size consistency smell and even color of a substance.

A Chemical Change is any substance that has a definite composition. Chemical changes occur when the identities of stubstances cahnge and new substance form.

A physical change is a change in the apperence of a substance, and a chemical change is when the substance is combined with another substance, to form a new substance. :)

A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.

the difference bewteen physical change and chemical change is thT physial change is the change of matter form one form to another withoout a change in chemical properties, and chemical change is a change that occurs when one or more substances change into entirely new substances with different properities.

The difference bewteen physical change and chemical change is that the substance on the object doesnt change which is physical like boiling water chemical is when substances changes and something new forms like salt.

the difference between physical change and chemical change is physical changes the form of the compound/chemical. Chemical is when the bonds have change therefore changing the molecule to another form

A physical change would be a change in state, such as solid to liquid, or gas to liquid. A chemical change is basically any chemical reaction, when two different compounds or elements react to form a new product.
Marshe Edwards

the diferentiate between physical change and chemical change occur when the identites of substances change and new substances form. physical change are changes in which the identity of a substance doesnt change.

Physical change alter properties of a substance, which includes breaking, melting and disolving. chemical change can either be released or obsorbed.

A physical change is occurs when the make up of a substance doesnt change, a chemical change occurs when the chemical make up of a substance changes. physical ex: ice into water

the differences between physical and chemical changes is physical change is the change in which identity of a substance and it doesnt change, a chemical change occurs when the identities of a substances change is new from the substances.

differences between physical and chemical changes are physical change is the change in which identity of a substence doesnt change.. chemical change occurs when identity of substence change is new from sumstances..

Physical change is when you can see it change.Like when you add die to water; the water changes color. Chemical change is when you add an chemical an the appearance does not change ,but the chemical does change.
