B) Mixtures cannot be separated by physical means.
C) Mixtures consist of only one kind of atom.
D) Mixtures have to or more substances mixed together, but are not chemically combined.
The change in the arrangement of particles as heat energy and temperature increase because of the increase in the kinetic energy of the particles.
Kinetic energy of any atom is calculated as:
K.E. = 1/2(mv²), where
v = velocity and m = mass
So, when we apply heat energy or increase the temperature of any system then the energy of the constitute particles is also increases which results in the increase of the average kinetic energy of the particle. Due to this kinetic energy particle will move with high velocity and disturbs the arrangement of the system.
Hence, due to increase in average kinetic energy, arrangement of the particles changes.

Answer:
there is more energy added as heat rises
Explanation:
Answer is: heat conductivity.
Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
__Cu(NO3)2 + __H2SO4 +
__N2O + ___H20
Answer:
50CuS2 + 260HNO3 = 50Cu(NO3)2 + 100H2SO4 + 80N2O + 3H2O
Explanation:
Answer:
An atom has the same number of electrons and protons because that means that it has an equal amount of negative electric charges (electrons) and positive electric charges (protons).
