Answer:
Induction
Explanation:
When a body is brought in contact with another, electrons are rearranged by contact.
When a body is rubbed against one another, charging by friction occurs.
The process whereby electrons are rearranged without direct contact with one another is called induction.
By induction electrons can get charged without them having to be in contact with one another.
- When a charged body is brought to the vicinity of the electrons, either an attraction or repulsion force is set up.
- Similar charges causes repulsion
- If a negatively charged body is brought near the electrons, there would be heavy repulsion and the electrons would be forced to rearranged.
- This effect is product as a result of a force field.
<span>A 1 molar solution is the molecular weight in grams in 1 litre of water, so a 3.5 molar solution would be 58.44g multiplied by 3.5, which is 204.54g in 1L.</span>
The new pressure will be
1000 L
, rounded to one significant figure.
Explanation:
Boyle's law states that when a gas is held at a constant temperature and mass in a closed container, the volume and pressure vary inversely. The equation to use is
