molecular forces binding them together is broken and the wax turn into liquid.
Hope this helps!
You could use the less malleable mixture of minerals. Say you have a gold earring this is bad because overtime it goes through lots of wear and tear, the shape of the earring will change. If it was less malleable it will withstand more wear and tear.
Answer:
Decreases.
Explanation:
The speed of the gas particles in the sealed flask in question here will decrease as it enters the freezer because the motion of the gas particles will slow down.
Based on the kinetic molecular theory of gases, the temperature of the gas is a measure of the average kinetic energy of the molecules.
Since the freezer makes substances cool and temperature drops, the kinetic energy of the gases will substantially drop. Kinetic energy is the energy due to the motion of a body.
Answer:
Sodium and Magnesium
Explanation:
The elements in Groups 1 and 2 get more reactive as you go down the group.
This means that Sodium is more reactive than lithium and Magnesium is more reactive than beryllium.
On the periodic table, as you go down the group, the reactivity of an element increases. Especially with metals in group 1 and 2. Now Lithium is a metal of group 1, followed by Sodium, while Beryllium is a metal in group 2, followed by magnesium. That's how I picked the answers
