Consider the statement:
“the temperature of the land is an important factor for the ripening of oranges, because it affects the evaporation of water and the humidity of the surrounding air.” how many of these factors, temperature
ripening evaporation humidity are chemical properties or changes?
a. 1

b. 3

c. 2

d. 4

e. none

  A. 1

Explanation:

A physical change is defined as a change in physical properties of a matter such as shape , size and its state ( Solid , liquid or gas ).

This process is a reversible process.

On the other hand a chemical change is defined as a change in chemical properties of a matter such that its composition gets changed . This process is irreversible.

Given Factors : temperature  , ripening , evaporation , humidity

Here,

Physical changes are : temperature  , evaporation , humidity because they are reversible, they do not form a new substance.

But ripening of oranges is an irreversible process because its a chemical change in it which makes fruit more sweeter and softer.

Hence, there is only 1 factor which is a chemical change.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
