Answer:
b. they can be observed and measured
Explanation:
Matter is anything that has weight and occupy space. There are three states of matter namely Solid, liquid and gas.
The properties of matter are both physical and chemical in nature. Both properties can be measured and observed. Phhysical properties are anything that can be measured without changing the state of the matter. Example of physical properties includes mass, volume, length, color etc.
Chemical properties is another properties of matter. This is the ability of the states of matters to combine with other substance to form a new product for example, rusting of iron, formation of salt etc.
All this as discussed are both measurable and can be observed.

I think u would add them all up and then write down your answers
Answer:
A. 60 Joule
Explanation:
First find the force given the pressure and area.
F = AP
F = 500 cm² × (1 m / 100 cm)² × 4000 N/m²
F = 200 N
Now find the work:
W = Fd
W = 200 N × 30 cm × (1 m / 100 cm)
W = 60 J
I know most of the answers will say infinity, but still this needs deeper look about its physical meaning and does it consider a practical logic?
Infinity usually used for something we could not measure, however the reality may be different!
