Answer:
evaporation
Explanation:
The process of evaporation is as a result of water absorbing energy from the sun.
The process is a phase change in which liquid water changes into gaseous form.
- The water in gaseous form is called vapor
- This water cools and condenses in the atmosphere as it loses the energy it has gained.
- For evaporation to take place, water must absorb energy from the sun or other heating bodies.
- This will then cause vaporization of the liquid water into a gaseous form.
Answer:
When most substances lose or gain energy, one of two things happens to the substance: its temperature changes or its state changes. The temperature of a substance is related to the speed of the substance’s particles. So, when the temperature of a substance changes, the speed of the particles also changes. But the temperature of a substance does not change until the change of state is complete.

*Answer:-*
The sun is about 1/3 the distance from the center of the Milky Way galaxy to its outer edges. It's located in a smaller spiral arm, between two large arms, called the Orion Arm.
Answer:
<u></u>
Explanation:
<u>1) Chemical equilibrium</u>
- 2Hg (l) + O₂ (g) ⇄ 2HgO (s) (the double arrow indicates an equilibrium reaction)
<u />
<u>2) Equilibrium constant, Kc:</u>
- The equilibrium constant, Kc, is equal to product of the concentrations of each product,each raised to its stoichiometric coefficient / product of the concentrations of each reactant each raised to its stoichiometric coefficient.
- Since the concentrations of liquid and solid substances remain practically constant, their value is incorporated into the constant Kc, and the equation only uses the concentrations of the aqueous or gaseous substances.
Thus, the equation to use is:
<u>3) Determine the concentration of O₂ (g)</u>
- M = number of moles / volume in liters
- Number of moles = mass in grams / molar mass
- Number of moles of O₂ (g) = 13.4 g / 32.00 g/mol = 0.419 mol
- M = 0.419 mol / 5.2 liter = 0.0806 mol / liter = 0.0806 M
<u>4) Compute Kc</u>
- Kc = 1 / 0.0 806 M = 12.4 M⁻¹ ← answer
