If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases;
- Its temperature increases
- The space between particles increases
- The particles move faster
Explanation:
As heat energy is applied to a substance, its temperature increases. The molecules of the gain more kinetic energy and the bombardment between the molecules increase with frequency and energy. The distance between the molecules also increases and this is attributed to the expansion of substances when heated. This continues until temperatures are reached where the kinetic energy of the molecules is high enough to overcome the intermolecular forces between the molecules and the substance changes phase.

Answer: water solutions conducts charge
Explanation: solid sodium chloride is n insulator.NaCl is dissolved in water
In ionic forms. In solution there are Na+ and Cl- ions which can transfer charge.
This problem is asking for the intermolecular forces in ethanamine, C₂H₅NH₂. Hence, after analyzing it, we find they are both London dispersion forces and hydrogen bonding.
<h3>Intermolecular forces</h3>
In chemistry, intermolecular forces are the responsible of holding molecules together both in liquids and solids, and they depend on the type of bonds exhibited by the molecule. In this case, ethanamine:
Has C-C, C-H, C-N and N-H bonds. Now, C-C, C-H and N-H are strongly nonpolar as they have an electronegativity difference below 0.7, which means ethanamine has London dispersion forces as the weakest ones.
In addition, the presence of N-H bonds, provides this molecule with stronger intermolecular forces, hydrogen bonding, which occur in N-H and O-H bonds.

Answer:
movement in tectonic plates. or volcanic eruptions.
Explanation:
Answer:
Explanation:
Given that,
The mass of a ball, m = 0.025kg
The force exerted by the magnet, F = 5 N
We need to find the acceleration of the ball when it begins to move. Let a be the acceleration. The net force of the ball is given by :
F = ma
Where
a is acceleration of the ball
so, the required acceleration of the ball is .
