Answer:
The solidifying/cooling and crystallizing of magma causes igneous rocks to form.
Answer:
Option B = 60,600 mg (correct option)
Explanation:
First of all we will have an idea which numbers are consider as significant.
1 = All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
2= Leading zeros are not consider as a significant figures. e.g. 0.02 in this number only one significant figure present which is 2.
3= Zero between the non zero digits are consider significant like 105 consist of three significant figures.
4= The zeros at the right side e.g 3400 are also significant. There are four significant figures are present.
In given options, Option A 60.6 mg have 3 significant figures.
Option B have 5 significant figures.
Option C have 4 significant figures.
Option D have 3 significant figures.
Thus option b is correct option which have more significant figures.
The answer is John D. Rockefeller.
Answer:
I believe it's (3)
Explanation:
same number of proton and electrons in both atoms A and atom B. but different number of neutron
Answer 1 :
Image 1 shows : Liquid phase
Image 2 shows : Gas phase
Image 3 shows : Solid phase
Image 4 shows : Solid phase
- Solid phase : In this state, the molecules are closely and tightly packed. There is no vacant space present in it.
- Liquid phase : In this state, the molecules are loosely packed and there is an intermediate vacant space present in it.
- Gas phase : In this state, the molecules are very loosely packed and there is a lot of vacant space present in it.
Answer 2 :
Liquid to gas : Evaporation
Solid to gas : Sublimation
Gas to solid : Deposition
Solid to liquid : Melting
Liquid to solid : Freezing
Gas to liquid : Condensation
Explanation :
- Evaporation : It is a type of vaporization process in which a liquid changes into gas phase by providing heat.
- Sublimation : It is a process in which a solid changes directly into gas phase without passing through a liquid phase.
- Deposition : It is a process in which a gas transforms directly into a solid phase without passing through a liquid phase.
- Melting : It is a process in which a solid changes into liquid phase by providing heat.
- Freezing : It is a process in which a liquid transform into a solid phase.
- Condensation : It is a process in which a water vapor(gas) changes into liquid state.
