When casein is added to HCl, it becomes a precipitate. It does this because of a process called acid coagulation.
The pressure of the steam leaving the can. the molecules inside the can are moving real fast due to heat being added , the molecules are innstantly slowed down causing the implosion
The vapor pressure of water at 50ºC will be greater than that at 10ºC because of the added energy and thus greater movement of the water molecules. If one knows the ∆Hvap at a given temperature, one can calculate the vapor pressure at another temperature. This uses the Clausius-Clapeyron (sp?) equation. It turns out the vapor pressure of water at 10º is 9.2 mm Hg, and that at 50º is 92.5 mm Hg.
It gains energy because the molecules are spread out more and moving at a greater velocity.
A simplistic summary of a very complex process would be: As heat is added to a solid material matrix, the kinetic energy of its molecules becomes greater than the intermolecular forces that hold those molecules. With this a change in phase occurs. For example, in a solid crystal, the molecules are held rigidly in position by the intermolecular forces. As the heat of the matrix increases, the molecules become more energetic and the movement around their equilibrium positions becomes faster and larger. Eventually, their enhanced motion permits them to create spaces in the crystal that other molecules can move into - the solid has now become a liquid (a different phase). As the heat increases even more, the increased kinetic energy of the molecules allows them to completely overcome any intermolecular forces and atmospheric pressure, and the material begins to become a gas and escapes the matrix. Cooling (removing heat) from a gas to allow condensation and then crystallization is the opposite process.
Air pressure becomes lower as water molecules are added to the air because water molecules have less weight.
have less weight
Sorry we do not know what you mean by "eater molecules".
have less weight
Air pressure is the weight of the air at a specific location. On the surface of the earth, we have the entire weight of the atmosphere pressing on us in the form of air molecules like O2, N2, and CO2. As we go higher and higher into the atmosphere, there are fewer molecules and so there is less weight pressing against us.
Yes Because the liquids molecules have to over come the resistance between each other
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
The pressure increases, and the molecules collide with the tire's inner surface.

Because the object becomes hot when heat is added.
