b. occupies space
d. is made up of molecule
a. has weight
c. can be seen
fixed shape and volume?​

Answer 1

Answer:

Fixed shape and volume is not always true

Answer 2

Answer:

has weight

can be seen

fixed shape and volume

Explanation:

firstly, matter is anything which has mass and occupies space and mass and weight are two different physical quantities.

secondly, it is not mandatory that matter can always be seen. for example, we know that air is matter but we can not touch or see it.

thirdly, it does not always have fixed volume and fixed shape because matter has three states and all of the three have different properties.

when we talk about solid, there is fixed shape and fixed volume but in the case of liquid, there is fixed volume not fixed shape(it takes the shape of the container it is poured into) and last, in case of gas, it has neither fixed shape nor fixed volume.
