Answer:]
Las propiedades de la materia incluyen cualquier rasgo que se pueda medir, como la densidad, el color, la masa, el volumen, la longitud, la maleabilidad, el punto de fusión, la dureza, el olor, la temperatura y más de un objeto
A spontaneous flow of thermal energy takes place from hot to cold. In order to flow thermal energy from a colder object to a hotter object, the work has to be implied on the system. The particle at higher temperature exhibits more kinetic energy in comparison to the particle at a lower temperature. Thus, there is a continuous flow of heat between the objects from the higher temperature to the lower temperature.
Molecules are continuously colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.
Answer:
An amphoteric oxide is an oxide that can act as either an acid or base in a reaction to produce a salt and water. Amphoterism depends on the oxidation states available to a chemical species. Because metals have multiple oxidation states, they form amphoteric oxides and hydroxides.Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide. Amphoteric oxides also include Lead (II) oxide, and zinc (II) oxide, among many others.[2]
