Answer:
The average kinetic energy of the particles in a gas is proportional to the temperature of the gas.
Explanation:
Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer.
The pressure will increase with decreasing volume. if they remain constant, that is.
The energy involved in melting in freezing is heat, At 0 degrees Celsius ice is at an equilibrium where the heat energy absorbed during melting (endothermic) and heat energy dispersed during freezing (exothermic). When ice melts its absorbs heat energy to change states, when water freezes to ice it dispersed heat energy so that the particles can move slow enough to be almost frozen, but still very small vibrations throughout the ice. Particles in the frozen state are packed tightly and help together by a crystal lattice and IMF's, liquid is free flowing with free floating particles that can move freely from one another particle.
Answer:
P + Q2+ -> no reaction
R + P2+ -> R2+ + P
Q + S2+ -> Q2+ + S
S + P2+ -> S2+ + P
S + R2+ -> S2+ + R
S + Q2+ -> no reaction
