Answer:
isolated system (plural isolated systems) (physics) A system that does not interact with its surroundings. Depending on context this may mean that its total energy and/or momentum stay constant.
Explanation:
An isolated system is a thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system. ... The system may be enclosed such that neither energy nor mass may enter or exit.
is there both?
There are two kinds of mixtures which are homogeneous and the heterogeneous. Homogeneous mixtures are mixtures that maintain the same uniform appearance and composition throughout; whereas, heterogeneous mixtures are mixtures that contain different visible substances or phases. Here are examples of each mixture.
Homogeneous mixtures: Rainwater, Air and Dishwashing detergent (This kind of mixture only shows one phase of matter)
Heterogeneous mixtures: cereals with milk, ice in soda and mixed nuts. (Obviously, this kind of mixture contains different phases of matter either in liquid, solid or gas).
Answer: She could have put a steel spoon into the vessel. The correct option is A.
Explanation:
When a candle wax is passed through heat, it is capable of melting within 10- 15 minutes of boiling. Therefore it is not capable of looking the same after 30 mins of heating.
When sugar is put into water it dissolves. When heated it has the ability to crystallize out after water is evaporated but doesn't retain its shape.
A piece of chocolate will melt the instance it comes in contact with any form of heat.
A steel spoon is an alloy metal which is not capable of melting by boiling in water for just 30 minutes. A steel is an alloy of Iron and carbon which melts when superheated at the temperature of 1510 degrees.
Bohr's
Explanation:
Experimental evidence of Rutherford best supports the Bohr's model of the atom.
Rutherford performed the gold foil experiment in which he bombarded thin gold foil with alpha particles. He found that most of the particles passed through with just few bouncing back.
With this knowledge, he proposed the nuclear model of the atom. The model suggests that an atom is made up of a positively charge dense center and a large space outside where electrons revolves.
- The Bohr's model of the atom was based on quantum mechanics proposed by Planck.
- He assumed the Rutherford's model and suggested that the extranuclear space is made up of electrons in spherical orbits around the nucleus.
