The answer is: the radiant sun.
There are five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).
Plasma is a an ionised gas with highly electrical conductivity.
It is an electrically neutral with positive and negative particles.
Plasma may be the most abundant form of matter in the universe.
Plasma was first described by chemist Irving Langmuir.
Plasma can be artificially made by heating a neutral gas to a strong electromagnetic field.
Answer:
Explanation:
Mass and weight are quite different terms .
Weight is defined as the amount of force exerted on the earth due to our mass and gravity of acceleration.
Given that the mass is 90 kg and gravity of acceleration of earth is 9.82 m/s^2.
So weight will be
So this is the weight of the 90kg man standing on earth.
Answer:
Density of the liquid.
Explanation:
Density is the mass per unit volume of a substance.
At specific volume of each immiscible substance, the substance with lower relative molecular mass has the lower density and such floats.
Thus, the physical properties that determines the solvent layer that will be on top is DENSITY.
The characteristics of a chemical reaction are:
The lower energy of reactants → Transition state → High energy of products.

We have to convert 0.18 km into feet
First, we need to know the conversions:
1 inch = 2.54 cm (exact)
1 pound = 454 g
1 Liter = 1.0b quarts
1 feet = 12 inches
1 galion = 4 quarts
1 pound = 16 ounces
0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft
Answer: 590 ft (2 significant figures)
