Why does ice cubes melt faster in hot water than in cold water?
because atoms in hot water vibrate faster, and cold water vibrates slower, hence movement generates heat, heat speeds up the ice cube's atoms, as the ice cube's atoms speed up it begins to expand, spread out it's mass and melt.
Why does conductor heat up when current is passed through after a long time?
Heating up means increase in average speed of atoms oscillation. When current passes through the conductor electrons collide (impact) with atoms and transfer a part of their energy to them increasing their average speed. Error: "average" instead of "average"
Why do most solids expand on heating?
That's because the molecules or atoms move faster, and in general have more energy.That's because the molecules or atoms move faster, and in general have more energy.That's because the molecules or atoms move faster, and in general have more energy.That's because the molecules or atoms move faster, and in general have more energy.
Temperature is a measure of the average kinetic energy of what?
Of particles, such as atoms or molecules.
A measure of the average kinetic energy of the atoms in a substance is?
The temperature. Hoped this helped!
What is the movement of atoms in a liquid during a temperature changes both increases and decreases?
As temperature increases, the atoms will move around more energetically - moving on average faster. Translational speeds increase, rotational speeds of the molecules increase, and the magnitude of vibrations of the atoms about their bonds in molecules increase As temperature decreases, the atoms move around less energetically - moving on average slower. Translational speeds decrease, rotational speeds of the molecules decrease, and the magnitude of vibrations of the atoms about their bonds in molecules decrease
What is fusion as opposed to fission and why does it need high temperatures and fast speeds?
Fusion is putting together (atoms ... usually hydrogen atoms), Fission is the breaking apart of atoms. And fusion requires high energy to occur because it requires the nucleus of atoms to touch (collide) - not an easy thing to do (basically impossible using only chemical energy).
Why is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
How many oxygen atoms are in a molecule of sulfuric?
Assuming you are talking about sulfuric acid, there are four oxygen atoms.
BIG BANG what happened?
Easy; a big bang. Two atoms hit each other at high speeds creating more atoms and matter, which eventually turned into the UNIVERSE. YAY.

What is an oxygen molecule with atoms instead of two?
I assume you are talking atmospheric ozone, which has three oxygen atoms in it's molecular structure.O3
Which element is the smallest?
If you are talking about individual atoms, it is hydrogen by mass or helium by radius.
What does it mean to say that opposites attract when you are talking about atoms?
it means when you have it you actually like it
Which is smaller atoms or molocules?
Atoms, because molecules are atoms bonded together.
What happens to to the average distance between the atoms of the copper when the rod is heated?
The space of the atoms increase!
