Answer:
Gas to liquid
Explanation:
As the atoms temperature decreases, the kinetic energy of the atom decreases. Besides if it is turning to solid the atoms will be fixed position,they wont pass each other. So it here is forming to become a liquid
Answer:
false; one could be in thin shape but thay doesnt always mean they are healthy, or fit...there is always a chance there can be malnutrition or they have a good metabolism, but to be in shape, there should be a good balance of fat and muscle in the body
Light as a wave
- Young's Double Slit Experiment.
- Davisson-Germer Experiment
Light as a particle
- Einsteins Photoelectric Effect Phenomenon
- Diffraction Phenomenon of Particles
<h2>Define the following terms:-</h2><h3>
1)Photoelectric Effect</h3>
Electrons are released when a material is exposed to electromagnetic radiation, such as light, and this is known as the photoelectric effect. These electrons are referred to as photoelectrons.
<h3>
2)Diffraction </h3>
When a wave hits a wall or an opening, several phenomena known as diffraction take place. It is described as the interference or bending of waves through an aperture into the region of the geometric shadow cast by the obstruction or aperture.
<h3>3)
Davisson-Germer Experiment</h3>
In the Davisson-Germer experiment, conducted by Clinton Davisson and Lester Germer between 1923 and 1927 at Western Electric (later Bell Labs), electrons scattered by a nickel-metal crystal's surface showed a diffraction pattern. This was an experimental turning point in the development of quantum mechanics and supported the wave-particle duality concept first put forth by Louis de Broglie in 1924.
<h3>4)
Young's Double Slit Experiment.</h3>
One of the most significant physics experiments was Young's Double Slit experiment. Thomas Young directed it in 1801. Despite the fact that Huygens' experiment had demonstrated that light has a wave character, the light at the time was still thought of as a beam of particles due to Newton's renown.

First of all, you have to write a balance equation for the reaction. The balanced equation for the reaction is:
CaCO3 + 2CH3COOH = [CH3COO]2Ca +CO2 + H20
Next, find the mass of the shell.
For an average egg, the mass is 0.05 * 50 = 2.5 g.
To convert this mass to moles, we have: 2.5/100 = 0.025 Moles. This is the mole of calcium carbonate.
To calculate the mole of ethanolic acid, we have: 50 * 0.001 * 2 = 0.1. This value is for 2 molecules, therefore for one molecule, we have: 0.1/2 = 0.05.
From the equation of reaction, one mole of calcium carbonate is required to neutralize two moles of ethanolic acid.
Thus, 0.05/0.025 = 2. This imply that two complete egg shells will be needed to neutralize 50cm of ethanolic acid.
2 C2H6 + 7 O2 -> 4CO2 + 6 H2O
<span>so the products are carbondioxide & water vapour</span>
