Liquids have more kinetic energy in their particles compared to solids. this allows the particles to move more freely, hence why they are fluids
Liquids diffuse from a region of high concentration to a region of low concentration, until equilibrium is reached
When heat is applied the particles gain more kinetic energy so they now have enough energy to overcome the bonds holding them in the liquid. this means they can evaporate off
Answer:velocity of molecules within a body
Explanation:
Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.
There are 3 significant figures in this value, all values before and after the decimal point are significant. As there is a decimal point, the zeros trailing are also significant.
Answer:
A chemical change because a temperature change occurred, the solid disappeared and a gas was produces
Explanation:
Magnesium reacts with hydrochloric acid releasing energy, and leading to the formation of magnesium chloride and hydrogen gas. This is represented by the equation below:
Mg₍s₎ + 2HCl₍aq)⇒ MgCl₂₍aq₎ + H₂₍g₎
