Melting, because it's spilling down and really what else could it be
Answer is: temperature of helium is -296,95°C.
The temperature T<span> in degrees Celsius (°C) is equal to the temperature </span>T in Kelvin (K) minus 273,15: T(°C) = T(K) - 273.15.
T(He) = 4,2 K.
T(He) = 4,2 K - 273,15.
T(He) = -268,95°C.
The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm<span> pressure.</span>
Answer:
b
Explanation:
because it is moving so it has kinetic energy
Answer:
Attractive force is predominant between the two atoms
- The two hydrogen atoms approach each other to form a bond
- The two hydrogen atoms start to combine to form a hydrogen molecule
Repulsive force is predominant between the two atoms
- The potential energy of the system is positive
- The internuclear distance between the two hydrogen atoms is less than the bond length
Attractive and repulsive forces balance each other
- The two hydrogen atoms form a stable hydrogen molecule
- The potential energy of the system is at minimum
There is no interaction between the two atoms
- The hydrogen atoms are very far apart
Explanations:
- <em>increase in potential energy causes repulsion</em> between the atoms, whereas<em> decrease in potential energy causes attraction</em> between the atoms
- in order for the bonding to occur, the attractive forces must be greater than the repulsion forces.
- The potential energy is positive when the repulsion forces is greater. This is because the distance between the two atoms is smaller than the bond length
- The potential energy of the system is at its minimum because the attractive and repulsive forces balance out each other.
